As far as quality of product goes, regardless of what people might say about different woodshops, PS Stix is still one of the best in the industry, so there is little chance you are going to get something that is cheap rubbish.
Everyone has their preferences, especially when it comes to BBS / PS Stix but as far as skating either board, I really don't think there is going to be much difference for the average person getting a new board, unless you are so tuned in with your setup, how you skate, what tricks you do, concave and wheelbase differences, which is how most people on here and other places will react if they set up something that they are not used to.
That said, it is also important to get a board, deck especially, that is the right size, for which there is also a lot of debate, to which some will say bigger and some will say smaller. For an average body size, weight, shoe size, anything from 8 to 8.5 is fairly common, with 8.25 being the most common size in skateboarding at the present time. Smaller boards are lighter and easier to get tech on, bigger boards will give you more room to move and balance if you are not so into tech tricks, or if you are a bigger body, taller, or just want something that will be easier to have fun on.
I won't go into too much more detail, but I think the number one issue I have seen from people getting boards, be it their first ever or first in a long time, is they tend to get a board that is often smaller than what they should be on, be it because the shop guy said that was the right size, or there were more smaller boards in the store, or just down to what graphic someone wanted, which only came in a smaller size.
Whatever the case, budget and ability are the two main things I would always ask someone before giving them options for boards, then go from there.
