What is it exactly that puts you off with your current crank? Is there an issue that your having or you just dont like the looks/brand name of it?
Because there's a few other components on your list that I'd change out first!
Basically I have noticed on the 09 reaper 1s is that it feels like there's alot of resistance to pedal. I've tried 5 of em. And they all do it. But if I ride a diffrent brand there's less.
Best way to put it is it feels like it takes way more effort to ride them.
Other bikes aren't like that at all.
Unless its not the crank but something else
Also I'm not the only one. I had a bunch of friends who rode lots look too and they said it def feels harder then it should be
It is a pretty low end spec, you have to ask yourself whether it's worth spending the money on a better drivetrain or a new bike. You could go for a X7, Deore or SLX drivetrain and brakes for $400 + ish but RS dart forks are not really adjustable so you would probably want to get something better which is going to cost $200 upwards.
Hub bearings, brake drag and gear selection all account for a hard pedal. I'd check those as well. Spinning your wheels while the bike upside down doesnt really prove much hub bearing drag. The real problem lights up when you put your weight on it. BUT, the crank bearing you can test when upside down to feel by hand. That will tell you if your crank bearings are causing the issue. Check in low gear with a freinds bike side-by-side as long as the tooth count is the same.

Even in 1st gear on my bike is the same resistance as 3rd or 4th on my friends Norco. Resistance is hard but if I put both in 1st an pedal at same speed I go same speed on both. If I coast they both coast equal. Only thing I didn't check is if the Norco has a longer crank. Which would give it more force. If tey are the same them I'm back to thinking its the crank
For a bike of those specs I think a Deore crank would be a good idea. They are available mail order for $65-$80 and come with the bottom bracket.
As far as the bike seeming slower, try coasting downhill with both bikes and see if there is a difference in speed and distance traveled.
I think I already states that but if not I have tried coasting down hill with both. I'm question if mabey that back hub is to tight as well
