Yes 1.0.2 will be more stable than 1.2.1, but not necessarily in the way that you mean.

Mozilla 1.2.1 has had a number of bugs fixed and internal changes made that make it faster, better and almost definitely less crash prone than 1.0.2 will be.

The stability advertised on the 1.0.x branch of Mozilla has little to do with user perceived stability (ie lack of crashes, freezes and data loss) it is more to do with the amount that the code inside Mozilla has changed. One of the guarantees that have made is that they will make very few changes to the way that Mozilla 1.0.x works inside and the way that it talks to external and add-in programs. This means that other companies that either want to use Mozilla as the basis that they create another application from, or make add-ons to Mozilla, can be assured that nothing will be changed that will make Mozilla incompatible with their program. Only small, low impact bug fixes will be made, nothing more.

This internal stability has a price, though and that is that the 1.0.x Mozillas will not have any of the big changes made to them that can make the browser suite faster, less crash prone and add great new features. These big changes are only made to the main Mozilla trunk which is where 1.1, 1.2 and eventually 1.3 will come from.

So the choice is between 1.0.2 which is essentially 1.0 with a few security and bug fixes, or 1.2 which has a whole load of new features in addition to the security and bug fixes. Of course you take the risk that these new features _may_ possibly have introduced other bugs.
