I'd go for the BOSS. I have the Yamaha, not the BOSS, but that's more about when I bought than anything else. The Katana range is a no-brainer, for beginners.
Whatever you do, do not get into tone chasing tube amps. Maybe when you get wiser about what to purchase you can, but now, no. Invest your money now so you can buy something really nice later. Tube amps may be pointless by then anyway. They almost already are.
Edit: Just to show you how stupid I am, this is what I'm looking at buying, AFTER telling you tube amps are almost pointless. Here's the ad. I'm thinking about making a low-ball offer this coming week. Next purchase, a very good attenuator and a Hot Mod to up the gain so I don't have to turn it up so much. Like I told the wife, it's like art, just looking at it will be enough. But when no one else is home, watch the #$^@ out! Yes, I like tinnitus. And I live in the country. Eventually, I'd put the cab in a separate room. You only live once.
