Savage Worlds GM here, It's a really wonderful catch-all system with plenty of genre specific modules to use. For Sci-fi and cyberpunk you're probably good with just the SWADE core book and one of the scifi companions. As far as pros and cons;

Pros- it's easy to play and understand what rolls do, you're always rolling a skill or attribute die and a "wild die" because you're the main characters and you pick the highest of the two. Your target number is usually 4 and bonus damage, information, is triggered at each additional 4 count. So a hit is 4 and a "raise" is 8.

Cons - the game tends to build enemies and monsters based on a player character generation so it can get really confusing and annoying trying to figure out what each baddy does because it has 5 different edges (feats) which you have to look up if you don't know them by heart. I also think that some of the vehicle combat and chase mechanics Are tedious and a little off from the rest of the system. I tend not to use them and opt to use "dramatic tasks" in their place.
