There's no question AP and Tak lead the pack at this stage. Probably a common argument about which is better but the truth is they are both superb.
I also prefer AP as they are super practical, overengineered (sometimes Tak is not engineered strongly enough). Optics are both superb. AP may go that step further.
My AP140 for example had a stainless steel drawtube that was quite thick and I think I could park my car on it before it would flex. Tak persists with all aluminium and its just too weak a metal for a super strong no flex focuser.
So often they are fine and occasionally they fail.
I am hoping CFF is the new AP. Time will tell.
