Tough choice.
Wallet - Obvious benefits with no negatives (unless you count losing your soul as a negative, I guess). Financial security would be very reassuring and, after some time to save up a bundle, you could do a lot with it, not just for yoursef but for other people.
Watch - Normally, I'd take the ability to freeze time over anything else without a moment of hesitation, but the limitation here kills it. An hour isn't a great deal of time to do a lot of things that freezing time would be most useful for, and having to wait two more hours before using it again just compounds the issue.
Spectacles - This is the only gift I have no real interest in. Not that it wouldn't be useful, just that everything else is more useful or appealing.
Ring - A ring that gives you a perfect memory, lets you learn basically anything really easily, and increases creativity? Yes, I would like to be Leonardo da Vinci. This one is extremely appealing.
Flask - I don't drink alcohol (assuming the flask only dispenses booze and not Ribena) but I absolutely would if the side-effect was perfect health and no need to sleep. As someone who hates their body and has constant trouble sleeping, this one has a very nice ring to it.
Gun - Basically a vampire. Tempting. I can live forever as long as I'm prepared to kill. I also get to have the perfect disguise as long as the gun is in my hand (assuming this works while holding it in a pocket or something). Immortality is alluring, but do I want a long life or an easy life?
Locket - Has obvious applications, but other gifts have much more to offer. It's not the worst thing on the table, but it's far from the best.
All things considered, I think I'd end up going with the Ring of Pride. Being able to learn things, develop new skills, and actually have the drive to do ****ing anything would be great. I'd love to
want to do stuff and be good at it. The Ring could even help you get the fitness benefit of the Flask, something similar to the money benefit of the Wallet, and the sex appeal of the Locket. So pretty cool, all told.
Suppose I want to keep my soul?
