I'd add Rivers Edge to the stands already mentioned.

What I've found I like in fixed position stands is rock solid attachment, big wide mesh platform, and a sling seat with arm rests. Sling seats are more comfortable, and the arm rests make me feel more secure when sitting way up there. Open platform with no shooting rail. Lot's on the market fit this bill.

Most seats will tilt back to the tree silently, which is a plus if you like to have room to move around and position for shots.

If you like what you build, have you considered just trying to improve on the cons? Identify and silence the source of the noise? That would be a deal breaker for me (I lost an opportunity at a huge buck once do to a stand popping when I shifted my weight. Never again...)

Aluminum instead of steel to save weight?
