Just looked at the Euro's trading history. 20 years ago you'd have got €1.75 for your pound and in 2008 it was €1.02.
The average rate over the Euro's 20 year history to 2019 had been €1.33, with it's 10 year history in 2019 being €1.20. Prior to the Brexit referendum it traded at €1.30, so all told this particular exchange is on a fairly even keel.
For goods and materials I'd be inclined to look more closely at strength of currencies in countries where manufacturing takes place, rather than those within which we trade with distributors.
