None of the comparisons make much sense when you are using seq versus mq as a whole.
Seq is a tool and mq is more of a tool belt. One of mq's plugins hacks into the game the exact same way seq does.
I think you can basically categorize plugins/luas/macros into 4 categories with differing severity levels of cheating for the most part.
Informational - existing ui enhancements, huds, mq2discoed, and extended intel via chat.
Enhancement of existing functionality - stick/chase, button master, enhanced maps (seq), some scripting could possibly fall here as it just expands on what you can do with socials while not being full on automation.
Automation - combat assist, twist/medley, eztravel/mq2nav, ts automation, quest automation, dz flips.
Actual memory mod - warp, far taunt, no fall damage, fly mode, perma eb, fast mem, ect
Theres some functionality that may not fall into any of those categories or be considered cheating at all like frame limiter and view port support that just enhance the client itself. I assume anyone loading mq is doing some form of automation but it's definitely possible to use it in the same sense seq user's use their software.
