Looking into getting a pump, I want to hear from people who've had experience

So I've recently been researching pumps and I was hoping to get some guidance from folks who have had experience using a pump or with multiple pumps who can compare them. Based on what I've read, my top two choices are Tslim and Omnipod. I like the sleek design and interface of the Tslim, looks like a smartphone instead of some kind of pager or some strange device. But I like the tubeless and watertight aspects of the Omnipod. Is the tubeless aspect enough of a difference that it should tip me towards the Omnipod even if I'm leaning a bit towards the Tslim? Also, I'm very skinny (5'11 and 120 lb) and I've had no problems with a Dexcom on my arm but could it be an issue with a pump? Would one pump be a better option over another because of this? And finally, I'm still in my honeymoon, which my endo expects to last roughly two years (diagnosed February of this year), so would a pump even be recommended or should I plan on waiting until my pancreas pooters out the rest of the way?

I guess there's a lot of questions there but I appreciate any response from anyone who can give me any insight/advice. Thanks!
