I prefer SP for the following reasons :
1. there is no latency problem , i can run the game smooth . i often play at the edge of surviving/taking high risks so problems like "lag" are not acceptable.
2. i don't need to share the loot . if i find a nice SU , it belongs to me , not to who picks it up first or whatever rule you make with those you play with
3. i can have a big stash to store all the usefull things i find/i craft (plugy) . I can acces this stash with any character to get the desired items when needed , instead of complete wipeouts every 2 or 3 months that will make you start over with your farming
4. i believe that if the game is designed that way that you can beat it by youreself , there's no need for a team to make it easyer for you , it would be like like playing in "easy-mode" (you farm /players 8 anyway by youreself ). i prefer all the glory for myself when i get the charms /find something rare/etherial
5. if i don't have time to do re-runs in certain places , i can save precious time by duping the items i need / consumables as arcane crystals / signets . this way i can have strong builds in very short time , instead of investing many days into endless farming (even if the drop rates are a bit better in SP) . i used to farm like a no-lifer some years ago , untill i had what i wanted , i know what that is all about and what time would it take to get "x" or "y" , but no more . my gaming time is short , so for me SP (duping) is the only way to go . My real life and job no longer allow 10+ hours/day free time to play
6. i don't need a ladder to tell me that i'm good at what i do . i can get all charms without much pain in the ass because i know how the game works/what strategy to take , things learned during my almost 10 years of experience with Median . there's no competition . i just play this game/other games to relax after work .
@no.5 this also allows me to play a large variety of builds and put new ideas to the test in real time . if they prove themselves worthy of something , i play the build again from zero to finish and if it's all ok , after all adjustments are made , a new miniguide comes out and i add it to the compilation, so others may try the build too .
i don't believe that during this life i'll have enough reasons to play on realm . i can live without realm-only content just fine

you can have that in SP too since forever . you can open multiple instances of the game and join lan game with another character to abuse of the same thing .
