Silvestrone's modpack is very good, let me explain why:
-it is an industry and magic based modpack with grate mods of its category like ars noveau and create
-isn't too heavy
-wide range of building blocks
-funny to play with (you can make a flute or a bubble blower just for tomfoolery for example)
The beginning might be slow, specially with the mods Ars Noveau and Create, but when the basics are learnt the game can proceed exponencially faster; using magic is very likely to be helpful and bronze is essential too; explore, farm and unlock new possibilities for building. Construct efficent farms to have tons of blocks and have fun even roleplaying. New foods are added thanks to Farmer's Delight so coocking can finaly become fun and not be just about keeping that stamina bar high.
