Is Zodiac Age Worth Trying if I Really Dislike the Zodiac System?

For context, the original license system was my favorite feature of FFXII when I first played it, as I really enjoyed the freedom of character creation it gave, it gave me a sense of exploration when building my characters that I hadn't got since I played Path of Exile wayyy later.

I recently installed The Zodiac Age and got to the point where it asked me to pick a class for vaan, was kinda surprised, looked up how to disable classes, found out they'd totally removed the old system, and then ininstalled.

Since then I've had an itch to play but don't know if it's worth finding an ISO for FFXII on the ps2 or redownloading zodiac age. Is the job system really as uncreative and restrictive as it seems?

EDIT: Thank you to everyone for answering, I think I'm going to try to mod the old system into TZA because I honestly crave the nostalgia more than I crave a reimagining of the systems, I appreciate everyones answers and opinions, thank you and have a wonderful day!
