I'll throw my 2 cents into the mix:
I've been on pumps for 22+ years. Been type 1 since 1970. I'm totally sold on insulin pumps. And a pump connected to a CGM brings it up to another level. Extremely easy to take the meal time boluses. No carrying alcohol swaps, needles, pens, insulin, etc. Count the carbs, input carb number and it is done. The pump calculates the amount of insulin. Same for corrections.
Tubed or tubeless ? General consensus is for tubeless from what I've seen. I've always had tubed pumps and I don't see myself changing this coming November. Failure of the pump itself is extremely rare. I have had 3 pumps changed out by Medtronic during the 17 years I used Medtronic. Weren't total failures either. Like an error code given. Pump was still working. Called Medtronic and I had a new pump the next morning in each case. Customer service was excellent. Coming up on 5 years with my Tandem t:slim with Control IQ and have not had a failure of the pump at all. The issues that are for me is the interface between the infusion set and me. Bent canula in the infusion set or placed in an area that doesn't want to absorb insulin for whatever reason. Usually scar tissue from years of injections and infusion sets. Easy to change an infusion set with a tubed pump. Tubeless requires a whole new pod and wasted insulin. Plus contacting the company to get a replacement pump.
I heard of the iLet pump about a year ago and it is pretty much a hands free device. No carb counting. Just input if the meal is small, medium or large. That's where it takes time for the pump to learn what your definition is of meal size . That pump must be used with a CGM. And my understanding is, perhaps the best a1c one can achieve with the ilet system, is around 7. Which is an average of blood glucose of 154. Perhaps someone on the iLet pump can chime in with better insight.
You mentioned that the tendency for more lows with the Mobi. The Mobi runs the same algorithm as the t:slim with CIQ. I have not been awaken with a low blood sugar since getting the t:slim in November, 2020. Morning glucose readings 90-115. YouTuber "Diabetec" last video was using the Mobi. His likes and dislikes. But he has always been a tubeless guy and is sponsored by Omipod. Though I think his reviews are fair. He doesn't like some of the things about Omipod either.
BTW: My Mayo Endocrinologist recommended the Tandem pump to me. Really glad he did because I wanted to stay with Medtronic. Medtronic pumps have been very good but their CGM's have not been getting good reviews at all. Hopefully the Medtronic users with get a decent CGM. Believe Medtronic is getting an agreement with a proprietary Libre sensor.
The best to you in your selection process. Take care.
