I think their a toss up.
I have 3 different brand panels, one of each you mentioned, and one no name.
They all work great in parallel together.

They look, spec, and cost pretty much the same, I'd go by which fits your situation better. The 2 mono 100w panels I looked at are different sizes. The thinner Renogy panels would work better for me.

I'm very happy with my 4 panel Renogy kit. I chose their kit because I have a small 5th wheel and their 100 watt monocrystalen panels where the perfect size for my roof, I can easily put the four of them up there and have room for at least 3 more.

Their service was excellent and a bad MPPT controller remote monitor was replaced quickly and easily.
