I am sure Logic plugins are very good.
I would suggest that you get really similar with stock plugins first. If there is something needed in particular - look for free plugins first. After all you can buy anything anyway 😉
Stock plugins may be more simple workhorses 🙂 Many commercial plugins are designed to match real hardware.
You may have not that plugin as stock plugin in your DAW or stock plugin may have not so may options (for example EQ in Cubase 7 LE was only 4 band EQ)
