I understand the differences between the two models, what I am unsure of is what model is best for troubleshooting. In other words, if I am going to learn a model inside and out, am I better off learning the OSI or the TCP/IP model? Which model is more commonly used in businesses? Is the OSI model becoming outdated?

The OSI model is not outdated and most used especially during troubleshooting. You will learn how to troubleshoot things like why your PC is not connected to the internet, networking, functionality of applications, connectivity, routing, and in general a great deal of the basics. -

(Of course, it's not an either/or game, and it's possible to learn both like most engineers.)Is the OSI model becoming outdated? -

It's a TCP/IP-dominated cyberverse, so you need both.
