Comparing 20" wheel size and offset

[Jcndsu]

I have found a wheel I like but the problem is the size I want is backordered 8 weeks. I wanted 20x9 with 10 mm offset. My question is would I be more happy with 20x10 with 10 mm offset or 20x9 with a 0 offset. My truck is a bighorn without fender flares. My tire will most likely be 275/60 unless I decide to go with 275/65 again.
Thanks

I would not put 275s on a 10" wide wheel. My personal opinion.
