Did you get any guidance from your consultant about what pumps are on offer from your clinic?
There is little point researching all pumps if you do not have access to them.
Maybe your consultant is asking you to do research into features that are available to work out what is important to you.
For example, do you want a tubed or tubeless? Do you want closed loop or not? How much insulin do you use for 3 days (the typical time between set changes) - different pumps have different maximum capacities. ...
As regards to advice - my main one is to not expect pumps to do everything and to be ready for needing to make changes - it is unlikely you will get all the settings correct at the start and they will change. Just having a pump will not reduce your HbA1C - you have to put in the effort.
Learning to use a pump is like starting to learn Type 1 diabetes again but I certainly find it is worth it.
