Well heres my breakdown for each phone:
HTC Rezound
Pros: 720p display, beats audio, great build quality, 32 gigs included, ibeats earphones. Ipod broke couple of months ago and this would be great replacement.
Cons: Recently broke up my gf of almost 4 yrs and she had an htc sensation and everytime I see the rezound it reminds me of her!!! Its the thickest 4g phone on verizon lineup, the screan looks smaller than the top phones like droid razr, spectrum and Galaxy nexus, it has poor viewing angles as well.
LG Spectrum:
Pros: Love the 4.5 HD display! it has great viewing angles! I think it has the best display of any phone on verizon right now! Love the design of the phone even though the cover is very glossy and plastic. Its lightweight and thin compared to the Rezound. It has Dolby sound integrated. phone can be rooted
Cons: LG interface is suppose to be the worst! Very laggy at times! Internal storage is only 4 gig with a 16 gig sd card. Phone not a status symbol compared to Droid Razr or Galaxy Nexus
