A standard HDD won't even use the max transfer speeds that SATA 2 can support. Boot times and such would likely be much slower on an HDD compared to an SSD also, though it varies how much depending on what drives and hardware and such.
You may be able to find boot times for those 2 drives online and compare the two.
Western Digital and Seagate are more or less similar in terms of reliability. Some people will be die hard Seagate or WD fans, kinda like the Intel vs. AMD and AMD vs. Nvidia deal, though there really isn't that much of a difference in the quality of WD vs Seagate drives.
I would recommend the Seagate simply because it's got much more space and cache. Some drives by both manufacturers are unreliable, but assuming a similar market (I.E WD black drives vs whatever the Seagate equivalent is) they should be similar in reliability.
