Low power: Pentax 40mm SMC XL gives 3deg. True FOV in TV102 with sharp image almost to edge. Very impressive on Pleiades and other open clusters.
Have no experience with your other choices. My High Power is a TAK 5mm LE. It's a gem and much cheaper than the zoom Nagler, but not nearly as versatile. I'd like to try the zoom Nagler someday myself.
My 22mm Panoptic doesn't see a lot of use. My 12mm UO Ortho does. UO Orthos below 9mm have very short eye relief and are tiring to use. But they are sharp, bright and cheap.
