Tripod discussions are like oil discussions....
Seriously, buy the absolute best one you can afford up front. We've all been down the path of a cheapie, then a newer one, then upgrade that until we've got four or five of them and only use the best/latest iteration. Just suck it up and purchase big up front. One and Done.
There's three pcs to the equation. The tripod, the ball head and the mounting system.
Tripods, you can think about metal or composites, overall height, does the center section extend vertically higher, does the head allow to re-orientate the shaft to shoot horizontal, clamps or flip levers to open/close the legs and will the legs go really really really wide to get the camera down on the ground.
Ball heads, you can think about x, y and z movement capability, micro adjustments, locking mechanisms
Mounting systems, you can think about standard Bogen plate types, quick releases, ARCA Swiss and others.
Yeah, it's a lot to take in......
