Which of my teams will allow more more arena success

Blixion

I have my trusty Rogue One rebels team, all at G8. Jyn, Cassian, and K2-SO are 7*, Chirrut is 6* at 70/100, and Baze is 4*.

Or I have my favorite team - First Order.
Kylo and FOO are G10 7*, FOTP and FOST are G9 5*, and Phasma is G8 7*.

Which would be better in arena under current conditions? I know FO defense isn't great (it's horrible), but would it be better than the lower geared rebels?

Note: Omega's on all Kylo's and FOST's abilities. No other omega's on any character.

I run FO om my main account and Rogue One on my alt. The First Order squad is able to take first at payout in a Dec 16 shard, but my Rogue One squad has a harder time and I often sub in Wiggs and R2.

Most folks are betting FO will get some new toons released with the next movie.
Here's my lineup if you're curious.

@tharduskafka I sit 250-500 in my arena. A slight nuissance is that I started in Dec 15, played for a week, and quit until March of 17. I'm a tad behind, but I hit level 80 yesterday, and I'm trying my best.

Well, I'm part of a First Order chat, and the guy who started it runs FO on a 2015 shard and is able to get first. They need four Zeta's, but the gear isn't as bad as alot of squads and they are super fun.

The worst part of FO and staring FOST and FOTP. They do well on offense, but slide easily on defense. They are an investment, but are also a ton of fun to play.
