If you're not on TI count, yes soloing is a lot faster and more effective provided you are killing things fast enough, in an AOE, and you are keeping your HP / SP up somehow that doesn't require sitting (nobody sits for HP/SP anymore). If you are on TI count, the reward already pays off the 400 (+400 if VIP) monsters you kill. But you might wait the same amount of time for a party.
Anyway, gramps does make things a lot easier and organized, but every player realistically should try out soloing sooner or later to really learn how the game works.
A Sorcerer shouldn't really die with Kaahi on, especially not at Juperos. Make sure you have proper reducs, like a good shield, and immune (or deviling!) garment. TSoD + Skull Cap combo is good but there are also cheaper options if you want good cast reduction. You can also opt for high DEX for fast cast too.
