Does anyone like Wit and Wisdom? 4th grade?

Considering transferring my kid to a school that uses this (I am also a teacher). It's a stronger school academically, but I'm worried it's a lot less fun. My kid is on/above grade level in reading in math - but his spelling and handwriting is terrible - they need attention (mostly due to lack of effort). Will W&W kill his love of ELA? Is there room for cool projects? He's currently at an IB school which is lots of fun but also way less rigorous and a lot of the kids are low level. Not sure I should keep him somewhere I know he's happy, or put him in the better school where he will be asked to perform at a higher level (which would be good for him).

But, I have seen the EL curric and absolutely hate it. Personally I loved the Lucy Calkins R&W units (while understanding the lack of phonics was a problem). I do NOT believe all these rediculous worksheets and charts and 10 different materials are what the kids need. But, my kid will be interested in the 4th grade modules - he loves survival and myths. But he also needs hands on, meaningful work.

Sorry for rambling...
