The problem with either method is that they lock the tables and it is not practical for databases that one wants to keep it available for 24x7x365 basis. For very large tables, while the tables are being reindexed, there will be many waiting update/delete/insert processes and this is not at all desirable.

That is not true. If you have a proper vacuum strategy then you should
be able to maintain a specific level of growth that is directly related
to your dataset growth.

In short if you vacuum enough, you don't have to vacuum full.

Not how this list works, your options are:

1. You only receive the reply
2. You + the list receives the reply

Most users opt for 2.
