i believe chrome and jetpack are quite the same in their simplicity. google even said that in the future they hope to make chrome and jetpack esxtensions compatible. regarding chrome's speed , firefox is starting to implement the multi-process browser ideas from chrome(a tab per process,a tab per extension) , with some of it is even in firefox 3.7 nightly build , which i feel is faster.
