Depends on the package you opt for, but, Proteus is used in UK universities, it has some nice simulation features, the schematic capture is fully capable, and is very intuitive, creating parts etc is quite simple.
The layout tool "Ares" is missing some features for high speed design, but it is fully functional and is very easy to use. I used it in industry on V7, I have used V8 for testing purposes, and it is not much different.
Overall a good package for the price (£4k for the "platinum" I think), the autorouter - meh, if you set it up correctly it will do a decent enough job, if you even use the AR, most don't, many will tell you it's a sin, I am an occasional sinner and it has produced workable results every time, then, most other packages have also.
Their support, though i've never had to use it, seems to be very good, they seem to have a dedicated team of support engineers and they answer quite quickly through their forums, they have a YouTube channel with various videos.
It has the usual 3D view, Gerber viewer, older graphics chips used to cause issues with drawing, not sure that is an issue these days.
IMO it is a mid level package, comparable for me to something like CadStar, and if I were going to recommend a PCB "food chain" it would go something like:
KiCAD -> DipTrace / Eagle -> Proteus -> Altium or OrCAD
KiCAD being free, but very very usable, DT/Eagle being low to mid range, i'm sure you can read the discussions on these on the forums, if you have a spare year to sift through all of the divided opinions!
Proteus is one of the best for simulation (of PIC's) and has a decent layout and capture tool, the only thing missing is as I say, high speed design, diff pairs, length matching etc, and Altium and OrCAD are on their own level.
Gerbers are simple to create with their CAM processor, if you post your project I am sure someone could if you needed it, create Gerbers for you.
