PC and consoles have their advantages and disadvantages. You should be familiar with both to be able to make a good decision. Surely what matters the most is the games you want to play and the costs involved.
The good sides of the consoles are many. They are less expensive compared to computers, they do not require a lot of technical knowledge to operate them and install games, there is no need of an operation system (which costs money), there are no drivers to install and update.
Consoles have several disadvantages as well. First of all you will not be able to change one or a few of the console components. If something breaks or if it needs upgrade you will have to change the whole console. Moreover consoles are created for game play only. Some really have additional features but generally speaking consoles are for games while a PC can be used for various things. Finally although there are many RTS games available for console playing, there are much more available for computers. Of course you will not be interesting in playing all of the RTS games ever created however to avoid disappointment you should check if your favorite real time strategy games will run on the console you want to buy.
On the other hand computers provide a larger variety of "things" you can do. You can work; you can listen to music, watch videos, and play games of course. Another advantage of the PCs before the consoles is that their hardware can be upgraded easily and replaced easily if something breaks.
The downsides of a computer are, as mentioned their high prices. Moreover you will need at least some basic knowledge to be able to install and set up your RTS games. In many occasions it might be hard to make a game run smoothly even though your computer matches the requirements of the game.
On the other hand computer RTS games have better multiplayer features than console games. The downside is that it is hard to gather several of your friends in your living room to have a crazy RTS game session while with consoles that is much easier.
