I’ve never been on a pump, nor have I personally had to use any of the older insulins, as I was just diagnosed diabetic in 2011 and put on insulin pens in 2013. But between 1999 and 2003 I was caregiver for my late husband after his stroke and he was on the older insulins. The newer analogs are so much more predictable that there is just no comparison.
If your insurance will cover any of the fast-actings, my preference is for Apidra. It starts acting faster. When my BG was elevated before a meal, my most frequent pre-meal dose of 8u would drop my BG by 30 points within 30 minutes. When I tried that on Humalog and Novolog, though, my BG didn’t drop a single point in 30 minutes, and in some cases not even in 40 minutes.
Apidra is also done with the insulin action faster, or at least it has been for me. I usually can get a good enough idea within three hours from dinner bolus to feel free to go to bed after a test based upon a BG reading at that point. Rarely would my BG drop more than an additional 10-15 points after that. With Humalog I had to wait four hours from bolus to test, and with Novolog a full 5 hours. Unfortunately, my insurance won’t be covering Apidra this year and it would have cost me an additional $1300 a year to go to a company that would, so I’m going to have to go back to Humalog after my current supply runs out.
You might want to do a search on a comparison of Novolog versus Humalog, as I’ve noticed that there are others who have a preference for Novolog.
I’ve only used Lantus as a basal and have no personal experience with Levemir. In an online course I took on diabetes through U of California, however, an instructor said that with Levimer, some type 2s can get away with taking only one dose a day, but almost no type 1s can because the duration of action is somewhat dose dependent and most type 1s use a small dose. I know a lot of people also seem to find that a split dose of Lantus works better than a single dose. But a single dose taken about 6 pm works just fine for me and I’m all for saving one jab a day. I take an unusually low dose of 8u, but I understand basal needs for “the elderly” tend to drop considerably and most younger people would be taking more.
