I went with empower since I decided to ignore T&B since I feel persistent is broke.
With T&B it would be persistent, then empower, then sculpt, then chain, then the rest come close to or just are sucking hard but can be useful in certain circumstances.
Widen is perhaps the lamest of the lame feats ever developed for example in all but some hey we fight armies campaign. +3 levels for the craptasitc ability of making the area of effect bigger, where all to frequently you don't catch more ofes with the spell and just make it harder to place without blasting comrades. Feat is a waste of space at +3 spell levels.
Quicken sucks butt +4 levels is so pathetic its not worth the ink they used. Sure in some very specific circumstances a quickened whatever helps out, but if its a feat and it makes the spell+4 spell levels higher it should kick butt all the time, not jsut give some solid benefit in a very small set of circumstances.
Maximise, heck even without stacking the smae metamagic is just a sucky empower. An extra spell level for smidge more damage, don't think so.
Extend well in 3e it was useful, in 3.5 they defanged it so much by suckifying so many durations its a sub par feat now.
The extra rang eone, well when it increased the area of effect of lines and cones it was useful, now at +1 spell levels it sucks beyond all comprehension of sucking.
Heighten has always been a bit sub par, if you have some DC fetish where you insist on increasing the DC of lower level spell instead of just using a different higher level spell hey this one is for you.(not bad idea for sorcerers who may not want to waste known spells on a better save or die for example) or if you bump into globes of invuln all the time(now with the improved 3.5 version not that kooky of a thing) then its somewhat useful.
Silent and still well they have there uses, vs grapples and silence spells, and some added stealth. They actually don't suck, but I'm not sure if its potent enough for a feat and +1 spell level. If you design your character aorund stealth well these feats are for you.
