I have several Smith .44 mags. I love the 44. I also have several Glocks. I don't love Glocks........except my Glock model 40 MOS. Darn, that thing shoots nice. Even with my ****** eyes the red dot turns it into a tack driver. With hot loads it's still a breeze to shoot. I'd shoot one before I'd rule it out.

If you reload the 44 has the major advantage of being able to easily find your brass. That can be important.

I can't tell you what to buy. How you plan to carry it in the vehicle can play a big part. For a car gun, a Glock 20 probably makes the most sense due to cost and capacity. If neither cost or capacity is a big issue then a Smith 69 may well make sense and they can be found cheaper than a new 629.

For hunting a 6" 44 or a Glock 40 or even a full size 1911. For just range work it's more of a whatever floats your boat and fits your wallet thing. There's a pretty wide choice out there.
