I suspect there are hundreds of programs that can deal with something that is, in the general scheme of things, a relatively simple application. I started about 20 odd years ago with IBM FileMaster, moved on to a more complicated DB program [name escapes me now] and when Microsoft came out with ACCESS database I switched to it as I also used it extensively at work. Access has become easier to use, especially in the context of adding card pictures to each record and it suits me fine. However if you don't have a more than basic suite of Office, it gets expensive.
On the Mac, I used to inventory a card game collection using FileMaker Pro - this was in the days before Mac OS X and Intel chips. I found it extremely easy to use. I've since tried the home version, Bento - it's not as flexible, but it's very simple. It's also cheaper and has an iOS app as well.
Databases are the way to go. You could use spreadsheets, even create calculations that cross to multiple sheets (on Excel, at the least, haven't tried it on Numbers yet), but eventually you'll reach a point where it's too much of a jury-rig, depending on the complexity of the data you're using.
Of course, if all you want is a simple list of "brand, maker, quantity", even Word is adequate for that...
Either way, MS Access for PC is a PAIN - I have to use it at work and I don't recommend it.
