I looked at both brands when we were in the market and ended up choosing the Stealth. For us it just came down to personal preferences based on style and design. I cannot say anything negative towards Attitude...just not for us.
We were looking at the 2212 floorplan, but decided to go with the 2313 because of the north/south front bed. We have had ours a little over a year now and have had no major issues, just a couple minor warranty issues; one with Forest River and the other with Cummins/Onan. We don't haul "toys" in ours so loaded for camping we weigh-in at about #7500-7800 range with tongue weight of about #1000.
