Bezie has some overlap, but the use case is a bit different. There are a couple of VSTs like LFO Tool and MIDIShaper that allow you to create a fixed width shape and toggle how many bars it should stretch over. In Bezie, if you select 8 bars, you'll literally get 8 bars to automate. As an example, if you wanted to map a couple different parameters to play with a song transition or drop, it'd make sense in Bezie, not so much in the others.
