Great, I've installed 6.5, and I hate it. now what?

Well, are we supposed to love 6.5? There are several things that I simply hate about it. the tweaks look like they would help the problems that I didn't have on 6.1, however tweaks appear to be just an ass load of work.
So, with that said, is there a way to just get back to 6.1, like I had before?
I thought that 6.5 was going to be better - yet it appears to use a lot more memory than 6.1 - I suppose that's why my phone freezes up often, and otherwise takes forever to switch from one program to the next.
I assume win mo 6.5 was made to be ran with a much faster processor, like the snapdragon.
Now what the hell happened to the pull down quick menu? I used that all the time to switch from one program to the next... now I have placed the task mgr on my home screen just so I can have some pathetic, degraded function of the quick menu??? which doesn't work with opera.
Should I want 6.1 back? is it really worse than 6.5? or rather, isn't 6.5 supposed be better than 6.1?
