Good luck on this new part of the journey! 
One of my very favorite things about pumping is the extended bolus! 
Pizza is still hard, but not as impossible when you can continuously deliver insulin over a long period of time!
If you have an endocrinologist and/or certified diabetes educator, they can be a good resource too! In my endo’s office, the CDEs regularly help patients learn to use their new pumps. I’m sure they can go over pros and cons with you, based on other patients’ feedback!
I use the Tandem t:slimX2. I like it overall! I’m on my third Tandem pump. I like that you can update the pump’s software without having to get a new pump altogether (until your warranty expires). However, it’s slower to come out with cutting-edge features than DIY AID programs, simply because it’s a commercial AID program that needs FDA approval.
The tubing isn’t an issue for me, even though I am certified clumsy. 9/10 times it’s my infusion site itself that catches on something (a doorframe like CarlosLuis, my waistband, a desk… just last week…). 
I make sure to tuck as much tubing into my clothing as possible regardless!
You might see if you can get an insurance cost comparison of pumps and pump supplies for different brands too. Here’s a breakdown of the costs to buy my most recent pump: Pump options? - #7 by RachelMaraii Once the Tandem warranty expires you can keep the pump – but you won’t have access to customer service and updates anymore.
