It has nothing to offer except for some decent architecture, but if you care so much about architecture you can just look at pictures, no need to visit to see it in person. People are just like in any bigger city, they are physically there but not really there if you know what I mean, you won't really experience Finland if you visit Helsinki, just typical modernism & globalism taking the essence out of everything. Finland is about enjoying the fresh air and serenity of the nature (more than 60% of our landmass is forest), shitty food, getting drunk in the sauna with a buddy, hockey, skiing, arguably shitty weather if you hate wet and cold, etc. out of these things Helsinki will only offer you the weather and the shitty food, at least in smaller areas our produce is much better.

It's also incredibly expensive and the cost of existing in Helsinki just keeps rising, I already talked about how if you want to get drunk with your buddies in Helsinki, you're better off taking a ferry to Estonia to buy your booze there than to do the shopping in Helsinki.
