Any cutting implement capable of causing booboos is a booboo snipper. It started with scissors, moved to my pocketknives, and finally extended to my kitchen cutlery.
There is no choice - not a single one - you can make in this decision that won't leave you with that "what if?" feeling. No one wa-handled slicer will "have it all," so you'll second-guess your purchase the moment it's made and keep second-guessing it for years to come. Just pick one, stick with it, and torment yourself with regret instead of paralysis.
