First vape purchase, currently in analysis paralysis

So I've been researching heavily on what my first vape purchase should be and when I'm buying something I will use heavily I always look for the best and take forever to decide and get stuck. So I've been looking into these and was wondering if any of you could push me over the edge to just buy one of these fuckers lol Considering:

• Flowermate v5.0S
• Flowermate v5.0 Pro
• Boundless CF
• Boundless CFX
• Dynavap M
• XMAX V2 Pro

My budget is probably $150 maximum but I'd really like to spend less if possible. I don't mind spending $100-120 if it's worth it. I want something that I can use solo and for groups of 4 preferably. Discretion is a plus but not a major priority. No unique situations really, I just want to try vaping, as I've been doing combustion for a while. Also, I do not partake daily, usually anywhere from 1-3 times a week. I'd say if anything is the top priority is that I can use it with a group and durability since we travel around. Hope to find something soon, thanks in advance! :)
