However, I have found it rather sluggish and flakey.
Where are the images stored - if on a network drive that could be a problem. I have a similar i7 PC, less ram and have nor problems with adding or removing images from the queue. Almost instant even when there is a complex image edit filter present.
Have you got all 4 cores operating with QU, check Edit Preferences, Hyper Processing?
Otherwise you have a PC problem - AV or some other software running in the background hogging resources; check in Task Manager.

but I assume you can select other interpolation methods other than Fusion.
You can but that would be a backward step. Fusion is "world class" and better that anything anyone else can offer.
BUT, the Ultimate version is massive overkill. It has loads of image editing stuff I don't need
I wouldn't be to sure about that
Fred has already indicated some of the editing features plus there's excellent raw features. The refine screen may seem too simple for some who are used to a myriad of sliders, but it works. Custom camera profiles are available for a number of cameras, and if not for yours, not difficult to get one made by Mike.
If you don't think print logging is useful for an amateur, think about that again. I use it regularly, and also an amateur.
Even if you don't use all the editing facilities (although Deep Focus & Tone Targeted Sharpening are really a "must have"), you will find the more advanced print and conversion features of QU a great asset.
As an aside, I looked at a section of the Gimp manual on Colour Management. It's far less flexible that QU and also has what I think is an erroneous statement in the section on Soft Proofing. At least it introduces an unnecessary step: -
"the display can be switched into Soft Proof mode. In such a simulated printout, colors that cannot be reproduced will optionally be marked with neutral gray color, allowing you to correct such mistakes before sending your images to the printer."That is what is taken care of by using colour managed printing - the conversion "engine" does all that for you. Many image profiles will have a gamut much greater than the printer gamut and it seems Gimp would expect you to edit them!
