Will MyISAM type tables work better than InnoDB for large numbers of columns?

I have a MySQL InnoDB table with 238 columns. 56 of them are TEXT type, 27 are VARCHAR(255).

I am getting MySQL error 139 when users insert data sometimes. After research I found that I'm probably running into InnoDB row size/column size/column count limitations. (I'm putting it that way because the specific limits among those three things are interdependent.)

Docs on InnoDB give an idea of the limits. If I switch this table to MyISAM is it likely to solve the problem?

I understand the maximum row size of 65,535 bytes. I think I'm hitting InnoDB's additional 8000 byte limit somehow.

Switching to PostgreSQL is also a remote option, but would take much longer.
