Are you mag or stam? How will you use the character?
What he replied with is great for magicka that is leveling or just tooling around. Not good sets for serious damage since they are sustain sets and certainly the wrong sets for stamina.
If you need a crafted set, Julianos is a solid standby.
If a pet sorc, Necropotence is good boosting your damage through boosting your max magicka.
For a monster set, I like Illambris for general use.
Otherwise, I'd recommend checking build sites like Alcast's to see what they suggest. Alcast in particular looks at a variety of gear sets, since not everyone can get trials gear. https://alcasthq.com/eso-magicka-sorcerer-build-pve/
