which one more important?

Do I need a thermometer gun or a scale more?

You don't really need a scale. But a thermometer is important.

i do have a thermometer but should i get a thermogun.

If you can only afford to get one of them right now I would recommend getting the IR temp gun first.
You can probably find both of them for $60-70 combined.

I'd say a temp gun is really handy, and much more convenient as well. And most of the time you would not need a scale unless you are trying to keep track of their growth or meal sizes for documentation purposes for future transactions. But if you do have a ball that is off feed, I would really suggest getting a scale to monitor his health and weight.

Temp gun.

I got my temp gun for sale for $10 and an 11lb scale off amazon for $15. Why not both.

You need a thermometer you can trust. IR guns are no more or less trustworthy than any other. They have more issues in use as well. Scales are a good indicator of health weigh gain or loss especially with older snakes. If you have a reliable thermometer an ir gun is just a connivence get the scale if you don't ir gun that is a reliable one.

im going to get both the reason why I asked is because they ran out of stock yesterday for the temp guns now they restocked.

Personally I could do away without a scale, temps gun on the other end are a must.
