Welcome Aboard, Loonie!
Hey, it depends. Man, that's three times now I've used that answer in 24 hours.
The reason it depends is nobody knows if you've actually been shooting, say, a Ruger 10/22 and know firearms well, or if you've only been to the range once with your friends.
If you're really a brand new shooter, by all means, get a .22 first, and hands down the Ruger 10/22 is a SUPER first gun unless you're about 7 years old.
The SKS is a great buy on a "fun gun" though it's not a tack driver. All the good things the other posters said about them are true. You may love other rifles more, but the SKS is a great buy if you like to plink (it's not a real sportsmen's deer rifle or long range prarie dog gun, either).
If you were my kid brother I'd have you buy both for sure, but the Ruger first.
Bear hunting with an SKS is a bad idea. It might do the job, but even where legal, that's a position of being undergunned by design. Small black bears..... maybe, if you're good and have proper ammo. MAYBE. If you're going to kill something on purpose, use enough gun to do the job. If you're new to guns, play at the gun range awhile anyway before you try to start hunting with a firearm. We'll all be happier.
That advice about Ruger and SKS for guys new to shooting is dead on.
A cool thing is that they kinda sorta handle alike. The SKS is heavier of course, but they're both 10 shot semis (base model with no tricks) that point well and don't malfunction, are easy to care for, blah blah blah. Not target guns, but for fun at the range, hard to beat.
You'll get really great advice on this forum. Sometimes it'll be differing opinions, but they're given freely so you can weigh 'em out and ponder where you wanna go. Have fun!
