I cannot see any reason to hate AMD. Indeed, Intel is more deserving of 'dislike' due to their past dirty business practices. However, at this very moment and probably for at least the next couple of years, intel has the strongest CPUs on the market for most applications. If you want the best, well, you have to fork your money out and buy an intel processor.
Now, does this mean AMD CPUs cannot do the job? Not at all. They can do pretty much anything that the intel processors can do, just not quite as good across the board. Unfortunately, AMD seem to have lurched around like a drunken sailor, heading this way and that, and are in a bit of a flux, not releasing anything new in the top tier of CPUs (the cancellation of the Steamroller FX line, and almost certainly the Excavator FX line), so while the current Piledriver FX CPUs can still dance well enough, they are slowly, but inexorably, falling ever further behind intel, who is constantly releasing (incrementally) better CPUs.
Come Broadwell (the next intel release of CPUs), unless Broadwell somehow magically sucks, FX CPUs are cut by 25% or more, intel increases their prices by 100%, or suddenly every game released is expertly threaded for 8 cores, buying an FX cpu from the Piledriver range will be an odd decision for all but the hardest of hardcore AMD fanboys.
Will the cpus still do the job? I have no doubt. In fact, unless you are having an issue with your AMD cpu, I cannot see any reason not to wait around and see what this new AMD high performance release (scheduled for a couple of years time) is capable of. You should have saved up enough money for a new system by then, or, if the new AMD chip is rubbish, enough money for a jump to intel if required.
TLDR; I don't hate AMD. They are 'good enough' still and probably for the next couple of years at least. They are dropping behind though, and need to get back on the road if they want to compete for the enthusiast dollar.
If you meant the A series lineup, there is nothing wrong with them. Excellent chips for an all rounder PC on a budget. Good enough CPU with very good integrated graphics. And since you posted this in CPUs, I also assume you don't mean AMD Graphics cards, which I use myself in my i5 haswell PC and have found to work perfectly in all situations.
