I had an Aquaglide brand kayak for about a year. I sold it because it was only 9' long and therefore didn't track well. But it felt durable and stable.
In general I'd say any of the better brands should give you good service for several years. Sea Eagles are popular and they have a budget model as well as a bunch of nicer drop-stitch, high pressure models that will not flex as much, will track better, and will flex less than the budget one.
Currently I'm using an inflatable stand-up paddleboard, Vilano Navigator, with a Sea Eagle inflatable seat, mostly with a Bending Branches Loon canoe paddle. It's slow but tracks well and I can stand and paddle with the longer SUP paddle when I get stiff and tired of sitting. I don't go far, it's just a way to get onto the lake and exercise for a while.
If you have the money and you like the idea of using your legs some of the time, Hobie makes an inflatable tandem kayak with their footpedal Mirage drive. They are plenty fun.
