If you can't fix it, you don't own it.

Im not sure I'd go that far (and Im an owner of both). NMTB/QC30 has
positive drive but a R8 power drawbar absolutely whoops QC30 in tool change
speed ease. Push button vs having to yank on a wrench both in and out.
Its not really an improvement.

How long does it take to lower the table far enough to extract
well it might be faster for one tool jobs but 5 or 6 tools already touched off
might make the qc a better choice

I've got an Erickson QC30 on my Bridgeport CNC mill.
R8 does not maintain any accurate Z reference after a tool change.
So while you can change tools quickly, how much time does re-referencing
the Z axis use on repetitive parts?

Why? R8 uses a taper angle of 16.85deg. NMTB/QC30 uses 16.5943deg [both

I have a 200 Kwik Switch on my Wells Index, would not trade it for any
amount of R8. Like the cat series it is a lot shorter for tool

My random thoughts.
I have just started using the R8/Tormach toolholding system and find it
far more convenient than plain R8. Changes are as fast as grab a wrench,
loosen draw bar enough to slide tool holder out, put next

What is the taper on those holders?
I made a 600+ mile round trip last week to pick up a load of NMTB 30
tooling for $1,000. A very nice surprise was the lot included a
Kennametal Erickson quick change spindle from a Bridgeport. The guy had
swapped it for an R8 spindle so he no longer needed all the 30 taper
stuff. Didn't
