The trouble with pumps is that we tend to just know our own brands.
I am on Roche insight for example and haven't used a Medtronic. Here are my pluses /minuses for what it is worth:
PLUSES
Cartridge fill so no messing with tubes in bottles to refill
Bluetooth connectivity with blood glucose meter that suggests correction does or bolus based on your inputs re carbs, exercises
Customer Service and re ordering direct from Roche has always been excellent
When its gone wrong they've sent replacement stuff out promptly even over weekend
MINUSES
The bg meter gets out of charge very fast so have to charge it every night and now I have FSL I don't bother so rather than dosing via the meter I am fishing the pump out of my bra/pockets to do the dosing based on guestimates.
If you use lots of insulin then you will be changing the cartridge often as it takes 160ml (on the other hand this could force a discipline of changing the insertion site).
If you have a look at YouTube you will also find a few type 1 pump reviews. There's a few more Amazon sites that supply accessories like pouches or pump undies (sad reflection of the more people needing to treat with insulin I suppose).
I am moving onto to Tandem Basal IQ + Dexcom CGM which auto adjusts doses of insulin to nip hypos/hypers in the bud hopefully.....
Best of luck with whatever you choose.
