SharePoint, Epraise, My School Portal, or something else?

[rflook]

My school is thinking of getting rid of Firefly as we find it is getting a bit dated, the cost is rather high, and the functionality is bit 'clunky'.

We were looking at My School Portal as an option, but don't know many schools that use it. Other options might be to use Epraise, or build a SharePoint site.

Can anyone sing the praises of (or warn me away from) any of the above options or point me in the direction of some other options?

We are ideally looking for something that does seamless Teams integration, can share attendance and behaviour information, reports/grades and allow us to send forms to parents for them to fill in.
