Google Planner monthly keyword search vol. vs SEMRush

[CamperConnect14]

Hi, This is an example but if I enter 'architect

This is an example but the same thing happens with most keywords - if I enter 'architect cornwall' into Google Planner it tells me there's 90 searches per month. If I enter this into SEMRUSH it tells me there's 320 searches per month.

Can anyone explain the difference here - and is one more accurate than the other? Better still is there tool that's more accurate than either of these?

I'm completely new to this by the way and the answer is probably obvious.

Thanks!

I go in KeywordPlanner with same keyword and here are results that he show me. You can find them in link below.

So seems that SEMRush shows whole ad group sum for impressions. And you go in group and look only for specific keyword.
