So we are looking at about £300 difference for luxury servo drive??

What to do ;)
Thats £300 extra for what.? Ridgid tapping that you don't need.! Indexed postioning you don't need because no ATC.!
Controller will give you every thing you need regards speed control etc from G-code using VFD just like it would if Servo so don't see the point.
Only advantage I see is the indexing and possibly extra torque at lower speeds, but you have back gear so not problem.

Save the Dosh and spend it else where.!
