The Adobe CC suite is great, professional software. It’s not without it’s bugs, but the new features really improve it over the CS6 version.
You can pay $20/month for just Premiere or $50/month for basically the newest version of all of Adobe’s creative software. On the flip side, you can pay around $1000 for for the CS6 Suite, which is definitely still great software. But why pay more for older software when you can have the better, most up-to-date version for cheaper?
If the cost is too steep, which is understandable, look into Final Cut X ($300 I believe?). I’m personally not a big fan as it is a very different way of editing, but it is definitely becoming more accepted professionally. Although the basics of editing will always be knowing when, or maybe more accurately, when not to cut, it is still not a bad idea to keep up with the latest software and technology in order to make yourself more marketable.
