The Maratac AA and AAA are rebranded iTP / Olight (some of them have slightly different body styles). The old 9290 was also a rebranded iTP / Olight (in a different color). I haven't handled the Maratac Extreme series and I'm not 100% sure who makes them, but the AA version looks a great deal like the iTP SA1.

I haven't had great experiences with iTP / Olight lights, having had to replace a couple of tail switches on the 9290s and having had a lanyard ring break on one of the Maratac AAAs and similar issues with iTP branded lights. The Extreme series I haven't tried for myself, but I'm underwhelmed with the claimed performance at that price point.
