That is a great question that has no good answer. It really depends on what your priorities are and what you want the pump to do.
I was on injections for about 30 years (MDI since mid 90's) and finally just switched to pumping last month.
I had ok control for many years but was starting to find it harder and harder get the ok numbers. A1Cs were creeping in the low 7's. I finally got a CGM last year and with the CGM and MDI I managed to get an A1C of 6.3. At this point, the only thing I thought I could improve was my basal insulin. I was on Levemir and found there were always times of the day when the amount of levemir was just not right. My main reason to switch to the pump so I could adjust the basal rate at different times of the day and I could use temp basals for exercise. Last A1C was down to about 6.0 so it looks like I am moving in the right direction and it is definitely easier for me to get better control with less effort than MDI.
At first I did not want something stuck to me, but then after having the CGM on, and loving the results I was getting with it, I decided I didn't mind another device. I am using the Omnipod so it is really just having two things stuck on. It actually doesn't really bother me at all, except if I roll over on to it while sleeping
So maybe think about what you want the pump to do for you, and if it improves your control or makes your life easier, you will not mind so much having stuff stuck to you.
Most pump manufactures give a 90 day free trial period. So maybe my advice is - give it a try, see if you like it. If you hate it, there is nothing stopping you from going back to injections. If you don't try, you will never have an answer to the question "to pump or not to pump"
