Of the ones I can use is their any "better"unit or advantages / disadvantages of one over another

Use either the LSU 4.9 or the NTK, don't bother with the earlier Bosch units.

I have been using NTK on all my projects.

I would recommend the NTK if you are using leaded gasoline.

if you are using unleaded either the NTK or bosch 4.9 would be fine.
