Please advise.

Neither of these are excellent but Strathclyde is probably better for most people. See: Best MBAs for international students' placement http://www.find-mba.com/board/41143

I would look at the economies of the places where these schools are based, and see if either hosts companies in your preferred industry. 

I'll be the first to admit that I don't know a ton about the economies of these cities, but it feels to me like Glasgow would probably have more varied options than Leeds. Do some research on LinkedIn to delve more deeply into it.

But yeah, neither of these would be the best options for international students. Did you apply to any better schools? 

I have received an offer from Durham with no scholarship. So am not interested in paying the full tuition fees at these uncertain times.

And yet to get an update from Edinburgh.

Received an offer from Exeter as well.

I am thinking to select Strathclyde or Exeter. Please advise.

I suggest you read again our conversation in February.
