For a straight-blast fest, nothing competes with Time Stop. Assuming a mainstream interpretation of the rules, and assuming you have good high-level assault spells (Horrid Wilting et al.) then the damage capacity is immense. Buy or make a Rod of Greater Maximisation, maximise TS and two HWs and you can dish out an incredible 54d8+288 damage in a single round. Even with saving for half, that's going to eradicate practically all your foes.
Hide Life is not good: simply buy and scroll, cast once a be done with it.
Foresight is worse: IMO it's the weakest 9th level spell in the book. +2 to Ref saves and AC. If defense is your goal, Shapechange is the better option (and far more versatile).
Wish is similarly a no-no: you're not going to be burning 5000XP on a regular basis, and sorcerors want spells that are going to be useful every day, not very occasionally.
But what of Mordenkainen's Disjunction? If your fighting lots of ultra-level enemies, many of them will be heavily hyped. This eradicates all hype-spells 100% of the time and has a good chance of disposing of their magical items. It can penetrate that pesky Antimagic Shell (if you're lucky) and act as a guaranteed counterspell (well, I allow it to anyway). It short-circuits magical traps and barriers. If you have plenty of assault from high-level, and can fill some 9th level slots with metamagic, MKDJ is a solid choice.
