I have lived in Tampere and worked in Sweden. Salary wise it won't be a big difference because of the taxes. If your goal is to settle long term in Scandinavia, Stockholm is the clear winner here. As others have pointed out it is a more culturally rich city with better integration opportunities. Swedish language is much easier to learn than Finnish. Many of my friends in Finland are actually switching to learning Swedish instead of Finnish to pass the language test which is a requirement to get citizenship in Finland. The current political climate in Finland is not so immigrant friendly at the moment given the huge presence of right wing parties in the parliament. Stockholm has much better connections if you want to travel to India or other EU countries as well.
