The deal is a good way to guarantee good money so let's see some things:
-How many chips did you have?
-Players in the table...
-Type of the tournament
If we have the chiplead in the final 5 players for example, but the players are regulars and pretty good and is a regular tournament in deep blinds, and u are not confident that you'll win that good players makes sense to deal, but if u are confident, players, are good, but not totally good and u have a lot of info of they, and u think you'll take it down, just put some pressure in that players and fight for the big money on top..
Let's see onother example we are in the final 5, but we have less chips, for example sunday million big money on top, with less chips want to deal to guarantee more money, in big tournaments, for ex the 5 place is 300$ with short stack you'll win more than 300$ for sure, so is a good deal for you because of your chips..
Now icm ou chip chop? if you're the chipleader, you win more money with chip-chop, but normally the players only
accept icm, icm is more fair for everybody... so icm is a good option for everyone, everyone will be happy
Hope to help u with this
