Happiness or stability?

I'm 29F and I met a guy (A) 29M online who I seem to share a lot in common with. We've been on a couple of dates and I love spending time with him, he treats me well, I laugh and have a great time with him (we're not officially in an relationship yet). My family on the other hand introduced me to their friend's son (B) 29M whom they're trying to find a suitable bride for.

I went out with B, and although he's also a really nice guy, I have nothing in common with him, he's abit of a workaholic and our personalities are really different. However with B, it is more stable, with the intention of marriage within a year and we already have both our families approval.

A is also dating with the intention of marriage, but things need to work out first (we need to be in an official relationship first, then introduce eachother to our respective families, then talk of marriage if it all works out). Should I choose happiness or stability? We're all 29 so I'm looking for something serious
