Glad to hear it worked out. The Hitachi setup should last you for years to come. You have what a lot of pros have found to be a great combo - 15 for baseboard and heavier trim elements, and 18 for quarter round and thinner stock.
Wood screws are great for smaller framing jobs. I’ve found deck screws to be worth the extra expense, as the heads tend to strip out less frequently, and the heads don’t pop off as readily.
Also, you had expressed some concern over the plastic parts on the guns. Did they ever give you any trouble? I’d expect not, but just curious.
