Our Tahoe is needing a recharge. I don't doubt there is a slow leak, but for the time being I'm planning to charge it. Is A/C Pro a good option? I see many different R134A options. I assume they're all similar. Was gonna grab what I hear works. Curious on feed back from those who have used it

Check the shrader valve and ball valve at the A/C service ports. I replaced my whole A/C system, and when i went to re-charge, it was the $20 valve that spewed at me!
Give it the best chance and do as @YukonGTmaster said and do at least the shrader valves, leave on vacuum for at least 30-45 minutes to boil out as much moisture as possible.
But remember this, if the accumulator is old, it only works for a period of time, especially if system is opened up. Also, if the leak is somewhere else, the full pressure will leak faster than it will after the pressure gets lower because it is leaking.

It sounds like he's just topping it off, so likely no vacuum on the system and not changing any valves. Based on my experience adding freon without both gauges is a hit or miss proposition.

I learned the hard way and now drain the system, run the vacuum pump and introduce refrigerant through a manifold and weigh the last can so as not to over-charge the system.
always replace the high side fitting.. and I've found even with new ones, be careful with how you crank down the gauge fitting. just open it enough to see the pressure, not all the way. you look at them wrong and they leak lol.
low side I've not had. much if an issue with. these years high side is just awful lol
