Are jeans a good choice?

I only own one pair of pants I'm comfortable enough in to wear outside. They're dickies 874 flex work pants. I own a few pairs of sweatpants that I wear around the house, but none of them fit me right because I feel like I might need a higher rise.

I'm 5'11 and 215 pounds. I have about a $30 budget and I was planning to buy another pair of pants similar to what I have, but I saw rustlers jeans are $15 on amazon I could technically buy two pairs of those. I haven't worn jeans in years so I'm a bit concerned they might not be very comfortable now that the weather's getting hotter. I'm also not sure how they will fit on me, because it seems like a lot of pants I wear have to be pulled up constantly even if they're the "right" size.

Do you think jeans would be a good choice or should I stick with chinos, slacks, etc.?
