Being new to Android, I'm trying to find the best setup myself. I can tell you a few things I've noticed right off the bat between the two:
1) When a phone call comes in LPP only gives an answer button, the TW gives a slider. Not a big deal either way, just something I noticed
2) Something I do like about the TW is the bottom menu icons have a number indicating texts and emails. The texts indicator works, but the email one only works for a gmail account and not my other accounts that I have linked.
Probably my least favorite thing about it honestly.
3) LPP has a lot more configurable options and I like the calendar and facebook widget a lot more. It takes some time to go through all the options to figure out what stuff does, but it looks pretty powerful.
4) It may be really stupid, but I liked the nice color icons for the menu, I havent found a way to get the same nice colored icons back, there's probably a way to find them though.
