Help me, should I return my G3 for Z3v? topic

My 2.5 yo Galaxy S3 dropped dead, broken screen. Went into best buy and got G3.

Initially, I liked everything. I thought it will be bulky considering the size, but surprisingly slim and light.

First 2 days, battery drain prob. I disabled the touch sound which was probably causing wakelocks.

Then, still the battery kind of was disappointing but I was alright with it.

I loaded eclipse rom and it felt great overall. However, I didn't know that G3 had some lag issues.

I went ahead and saw Z3v in the store. Very snappy with the same processor compared to G3.

So I keep thinking, should I return G3(which was free with contract) or get a Z3v (0 extra money).

The positive side of using G3 : Unlocked bootloader, tons of ROMS, customizations, tweaks. Free with contract
Negative side: Still laggy on verizon models, battery disappointment

Positive side of using Z3v: Snippier phone, I like the design of the phone
Negative side: Z3v is essentially a Z2. However heavier than Z2 or Z3, so little bit bulkier. Locked bootloader, no root, tons of Verizon bloatware. It is a minority phone so that it won't get much attention and there is a chance that it will never be rootable. 0 extra money

Help me choose please?
