Wormholes

Hey can someone point me to a pros and cons list for c3/c4 vs c5/c6?

Or if there is none, run through the basics?

Afaik c3/c4 sleeper sites can be run solo therefore always something to do even if there are no fleet ops. but just less isk.

c5/c6 is more isk but you need to have a group to run the sites.

log on during the day and run sites like they were missions. pvp at night :)

Very vague list of criteria, so here is my answer based on your list:

C5 are better than C4s/C3s.

You need a great many folks to live in C6's. Security is an issue in those systems.
If you are into a lot of pew do it. But compared to other wh class fleet engagements are not uncommon.
You will encounter the large wh alliances often.

C5 got the advantage of being hidden among the many. Yet many c6's connect to c5's.

For both of them hold true that you need 4 cap pilots + assistance to make isk.

However, if that is an issue to assemble you probably will be kicked out.

C3's are very popular as they can be done by smaller operations. Somewhat more dangerous than c4's as they are often crossroad systems to larger wh chains.

C4 sites are a bit harder to do than c3's but have an advantage of obscurity.

Imo, for new wh's insisting on making mistakes by themselves and not joining and learning a wh corp a c4 with a c2 static seems like the best choice.

And lets just finish the list.

C1's are not worth the logistics. C2's most often cannot pay for your losses.

Unless you primary income is PI, static hi or low is NOT an advantage. You will want a static to another wh, else your wh will be gank haven for daytrippers.

pros: people who are good at w-space
cons: the dudes who steal everything of yours
