I like polyurethane most, since I dislike the repeat maintenance of other options, and like the resilience of polyurethane, but I find it's a pain to get it right - I usually have an algorithm of try, wait, sand it down to bare wood, try again, wait more, sand more, repeat a couple times until I'm satisfied. If you're okay with periodically re-applying, and don't need the durability of poly, something like tung oil is a great choice - wipes on super easy and looks fabulous. Sibling comment has great recommendations in this domain. On gumminess - it sounds like it didn't cure correctly? Could be environmental factors, (temp/humidity) could be uneven application, etc. I also find I have to leave polyurethane alone for a looooong time for it to cure properly - I try not to touch the final coat for a week or more. I try to do very thin coats, sanding between each coat, for 2-3 coats, then for the final coat I use a spray polyurethane which seems to lie flat a bit better.
