I use TV Delites, Delos, Panoptic and Ethos in my 12” F4.9 Goto dob and hardly even notice the coma to be honest ( unless your looking for it ) Although admittedly the view is slightly better using my Type 2 coma corrector set for each eye piece
My favourite eye pieces for Nebula , Galaxies and Clusters are the Panoptic 24mm , Panoptic 27mm and the Ethos 21mm
For planets the Delos 4.5mm, 6mm and Ethos 8mm
For Lunar just about any TV eye piece in my collection
All have a full set of TV Powermates for observing and for planetary and lunar imaging
I haven’t used any other eye pieces so can’t comment or compare to other high end quality eye pieces
My TV collection work well in my 6” f6 and 8” f5 imaging newts as well !!
I just love my TV collection
Cheers
