I have one of each in the house. They feel different. The squire is actually a *tiny* bit heavier to me, thicker neck feel too.

I like the feel of the MIM in my hands better. Slimmer flatter neck to me. But I wouldn't suggest this is better for anyone else. The sound is not quite the same, but the Squire is still the strat sound. MIM seems to have more of the bright capability. I could see this debate going on a while with differing opinions.. possible depnding on different runs.

The Squire has a tighter feel to the knobs on the one here, also. Very different rolling the volume between one and the other. Then again the MIM is much older too. Could be I'm just more 'used' to it.

I wouldn't buy a guitar without playing it first anyway. Even two MIM strats can feel different. I played quite a few in a few different stores before deciding on one.
The Squire is actually my daughters and she loves it. Doesn't like playing mine!

I do not work here, but the benefits are still awesome
Make your sound your own!
