What's the best ROM to flash for legend?

My wife is using one with the stock Eclair sense - and I am thinking to root her phone and replace with better ROM. Any suggestion?

Or maybe I should wait for Froyo OTA (which means by then more OTA based ROMs available?)

I'm only heavy on my mobile internet... its on 24 hours.... hahaha.... if i don't use my phone, i mean don't use the mobile internet, it can last for 12 hours... but if i do only 5 hours... i don't game... i dislike to play games on legend, i play em on ipod touch...

I have the same problem, decided not to bother with it and just add gmail's site on my bookmark, straight go to the site better, that's why I ditched the Mail app by the phone, it tends to lag my screen, eats space, and force close, A LOT. Now I have hotmail on my bookmark as well, one click solves the problem lol.
Lol like you said, on 24 hours, you need power to maintain it on LOL. 5 hours seriously? What are you surfing for ?    I try surf for 1-2 hours I already bosan lol, I sometimes open my music when it's about to have no bat, make the battery drain faster so when your on low low low battery, you charge again, at least that's what I do lol.
