Anyhow, I'll give you the (extremely) short version...
I have a Logitech G5. I've had it for years and it still works flawlessly. The company is no longer really supporting it with updates and the current Setpoint software hasn't allowed me to custom program the buttons, so I thought it was time for a change.
For the record, I'll say that I have medium to slightly larger than average man hands and use a "fingertip grip." If you don't know about the three grips — palm, fingertip and claw — it's worth reading about them so you have a sense of your needs. I was also looking for something other than Logitech, comfort, more buttons, a better sensor, etc.
I tried a LOT of mice. To give you a sense, I looked at CoolerMaster, Razer (though not all), Thermaltake, Roccat, Corsair and Gigabyte, multiple models from each. And I bought two — the CoolerMaster Inferno and the new Razer 2014 Naga — and returned them both. Not because they weren't quality or didn't work properly, but because they proved uncomfortable while playing. I also spent time gripping both the G700s and G500s from Logitech, and while the G500s' shape is very similar (though not quite identical) to my G5, both felt cheap in two key areas. The thumb buttons felt plasticky and hard to press precisely repeatedly. And the mouse wheel is way too loose, both for tilt and rolling forward and backward (and this is in notched mode, since both mice have a free scroll mode as well, as you know).
So, I'm sorry to say that I ended up back where I started, the G5. I found an older version of Setpoint that gives me total customizability of all the buttons again, and I'm staying put for now. I'm not saying you won't find another mouse with a shape that works for you — there are so many that you may, and who knows if your hand and grip are similar to mine. But I can tell you that nothing I tried really duplicates the Logitech G5's signature shape, even if it looks like it does.
So, the recommendation to buy a G400s isn't a bad one. Logitech quality is generally well regarded, even if you've had some issues. I know you just bought a Razer (and, as I stated above, I bought one too before returning it for nothing to do with quality), but there are tons of posts about how Razers go bad after not too long. There are also posts from people who've had theirs for years. Just know that mice die, and even owning a few isn't statistically significant enough to really judge that you should abandon the brand, even though it's completely understandable if you've had a couple of bad experiences.
I believe that the G400s is the most solid of the Logitech G series mice, and the closest to the G5 or G500 shape (obviously, as a former G500 owner, the G500s will be close to what you had too). The G400 also boasts an optical sensor, while the others are laser, and the majority of gamers agree that optical is better. It may not be too noticeable, so you might not care, but I haven't read anyone say lasers are superior.
That said, the Razer Deathadder has an optical sensor, and it's supposed to be one of the best. So that won't be an issue for you. The real concern may be the shape/feel. Many swear by that mouse...it's among the most popular of all time. So you made a good bet. But you'll have to see. It also only has a couple of buttons, less than the G500, I believe. If that doesn't matter to you, then you'll be fine, but it is limiting for those of us who play CRPGs or RTS or MMOs or MOBAs.
I wish I could tell you that another company makes a far superior mouse in the same Logitech shape. But I couldn't find it.
