Female betta sorority or Male divided? Pro's & Con's

[SparklE fin]

I'm getting a 15 gal. soon and I'm stuck with this predicament. I have no idea what to do! Can you list the Pro's & Con's please? Also don't say "Its up to you", it makes it harder

Sankyo!

if you already have males, then.... sorority! maybe 5 females and a few community fish in a NPT :) it'll be beautiful

Sorority:
Pro- Lots of pretty girlys
con-The price of decor
pro- It will be cool watching them interact
con-You will need to keep a close eye on them
pro-looks nicer then a divided tank
con-may accidently get a male or a female who can't live in the tank

Divided tank:
pro - Lots of pretty males
con - Might get a male that can't live in a divided tank
pro - Cheaper for decor since you wont need as much
con - They don't look as nice
pro- Its fun to watch males flare at each other.
