You might think this is a bit overkill but I have 4 different types of meter. I have a Glucomen Areo which my DSN gave to me while I waited for my diagnosis so that I wasn't having to self-fund my strips and lancets - which is what I was doing up until I was diagnosed with type 1. DSN then gave me an Areo 2K which I use purely for testing ketones. I also have an Accu-Chek Mobile which was my daily driver and also given to me by my DSN. In addition I have 2 Accu-Chek Instants, one I leave at work, and one is at my parent's. I self-fund the Accu-Chek Instant strips but get my lancets and Accu-Chek Mobile cassettes prescribed.
For the most part I would say the Accu-Chek mobile is the least finnicky to use and is the meter I use when I need to back up a dodgy Libre 2 reading, but you do have to be mindful that the cassette, once installed, does expire after 3 months, even if you have some tests remaining, although for someone who tests regularly like we have to, it's never going to be a problem.
At least with Accu-Chek Mobile you won't need to carry the meter and a separate pot of strips, it's all contained in the same unit. It also comes with an Accu-Chek Fastclix lancet which hold 6 needles in a drum, and is by far the best lancet I've used.
