I think you'll definitely get suggestions that include xtrROM or xtrSense (if you want sense of course). I like KaosFroyo personallly, but I don't think it will be as FAST as xtr (though its close).

 

xtr-sense is probably the best way to go, if you're looking for a faster HTC Sense experience. The rom is efficient and stable.

 

Try going to a Froyo rom. Cyanogen Taz 2.0 is a great ROM. xtrROMS are good for 2.1 as well.

 

xtrSense 4.0.6.1 will look very nearly identical to your stock phone, and everything works.

Buttery smooth, right out of the box. (Default OC is 710, iirc).

Zach.xtr mentioned the other day that he altered the default process harvester settings in xtrSense 4.0.6.1 to be similar to the settings that Autokiller uses in "Strict" mode.

In addition to OC'ing, that's why it is as fast as it is - the Android process harvester has been tuned to always maintain lots of free memory for file caching operations. That will mean that from time to time you will see the launcher re-painting the home screen - that's the price you will pay for all that snappiness.

As far as Froyo ROMs go, Kaos and Tazz current ROMs are essentially flawless in comparison to any functionality you would find in a stock 2.1 ROM - perhaps with the exception of the camera (I find the replacement camera app to be worse in features and autofocus capability).

2.1 Rom = xtrROM 4.0.6.1 [ROM][8/19/2010] xtrROM4.0.6.1 [apps2sd,jit,lwp,oc,flash10]-Vanilla that embraces HTC - xda-developers

2.2 Rom = KaosFroyo V31 http://forum.xda-developers.com/showthread.php?t=685594

Both very nice. Fast.

 

Cyanogen Tazz 1.0

Fastest 2.2 I have used so far. Battery life is also excellent.

 

Whatever rom you pick, trying installing the Autokiller app. Makes a huge difference on any rooted phone, especially one running a very close to stock rom.
