Yesi i would jump to the UD3H over the D3H b/c of the extra OC features. Also the UD3H has a better PCB(2oz copper). The Her from what I heard is a nice board, it isn't comparable to the M6E, but from what I have checked it does have the same VRM. Those chokes on that board are purely marketing, they are 60A chokes(to compete with GBT who used 60A hokes n their UP boards last time, however they are using a 40A NexFET, but only one per phase for all their ROG boards. GBT on the UD4H, UD5H, and UD3H and any ultra durable 5+ board is using at least 40A IR3553, which is equal in power delivery but the NexFET doesn't have integrated drivers like the IR3553, that makes a very small difference as the IR3553 would compete a fully IR made VRM(except passive components like chokes and capacitors)
here is the MOSFET(1) per phase that the Z87 ROG boards used: http://pdf1.alldatasheet.com/datasheet-pdf/view/461899/TI1/CSD87350Q5D.html
here is the MOSFET(1) per phase that the Z87 GBT boards except(OC Force, Sniper 5, UD7 TH) use: http://www.irf.com/product-info/datasheets/data/ir3553.pdf
Both MOSFET packages have 25A @ 90% and 40A max, now using two NexFETs per phase provide 50A at 90%(but Z87 ROG isn't doing this, there is little need for Z87), but IR3550 also does 50A at 90% in half the size with a driver. However this round it seems no one is using two NexFETs like X79 ROG Ramapge 4 Extreme does.
The GBT UD3H's VRM is thus very comparable to the Z87 ROG VRMs, except the Z87 ROG have 60A Chokes while the UD3H's does around 30-35A, however the choke only limits the MOSFET's current output, thus those 60A chokes are not going to get over 25-40A going through them, however they look pretty cool, they have a gold plating on their center to make it look nice. I think it is more of a what you see versus what is needed. But Honestly VRM isn't so important anymore, it just needs to be able to output a certain current which both boards will do.
Both Z87 ROG and all GBT Z87(D3H and up) use IR3563B which is a 8 phase PWM
Both boards use 10K Japaneses capacitors, ASUS from Nichicon, GBT from Chemicon.
I am not sure about the hero since andre called it a Toyota(Hero) Compared to Ferrari(Extreme), he said it lacks a lot of the extreme ROG features and recommended people get a Gene instead if they want to do LN2, but still not comparable to the Extreme, but I don't see why not.

Yea I agree with this.

What is the overall consensus on these boards? Is there generally better support from GB? If I'm going to be stuck with a board that has issues one way or the other, I would prefer to have one where the support is there and fixes are rolling out, not every 5 minutes, but consistently as real issues arise.
This is only my second build so I don't have much to go on in terms of mobo history and which company is the smart buy these days. I have nothing crazy going on with this build. Just looking to play around with OCing a bit more (965 was boring) and doing some gaming.
Thanks for any advice.
I can tell you that GBT is working very hard to get rid of any BIOS issues, they want their new UEFi to catch on so they are trying to work out compatibility right now, and they are trying to do it fast. So at this point they are working on things such as making HD BIOS(expanded version of the new BIOS) more compatible with more types of video transmission. I also do think the latest BIOS took care of some issues with freezing in the BIOS, it also made Unore multiplier work which caused some OCes to become very unstable as users were setting uncore before but it wasn't going above 39x. Now BDOS is windows is prob not the board, these boards have been tested a lot to make sure they don't have any of those issues(some GBT Z77 had BDOS in windows caused by BCLK being above 100 by default, any BCLk change needs more voltage, so with Z87 they tested the boards rigorously with multiple configurations and DIMMs). Regardless the reason you see so many post here is because that is what this thread is made for, for people to report all their tiny or large issues so that GBT can fix them, and I can tell you that they are making these issues a priority. I also think this is the place to get the help, I don't see many posts about GBT Z87 on other forums. I think you will like the UD4H.
There are still some memory incompatibility with certain XMP of older DDR kits, that is why there is a memory compatibility list on their site now: http://download.gigabyte.asia/FileList/Memory/mb_memory_ga-z87x-d3h.pdf
However as I report any memory issue here it should be fixed within the next few beta releases which at this point are coming out fast.
