The problem isn't that the legs are wobbly. The problem is that if you ever, ever, ever, ever move the grill by pulling on the front handle while rolling on the wheels, the leg flanges WILL BEND backwards. NEVER roll those wheels. Pick it up and carry it if you ever have to move it.
If someone offered me the choice of a free 26er or a 22.5, then I'd take the 26er.
If I had $300 of my own money to spend on a grill or two, For the same price, I'd rather have two 22.5 OTGs than one single 26er. More area to work with. More, better, cheaper toys and accessories.
