After reading @johnzo posts last year about it I also used a server from the Netherlands, but my plan this year is to look at the list of available countries and favourite them in my VPN (I use IPVanish) so I can just choose whichever has the lowest latency at the time.
The only issues I had with the stream were on my end. I live in Northern Alberta and my internet speeds would routinely drop below 5 Mbps. When my internet speed was even marginally higher than that the stream was great. Over the winter we were ungraded to lightning fast 15Mbps (sadly that is considered fast for our neck of the woods) so I'm expecting no issues this season. Sorry, don't know about bandwidth.
Like @johnzo said, there was one game that didn't show up in the archive until much later but other than that my experience was they showed up within an hour or two, often sooner, after the game ended, and the vast majority of the games I watched were archived.
The Bomber pass is perfect for someone like me who only has time to watch the Bomber games, and usually from the archive rather than live. Not sure if TSN will allow you to watch archived games or not, but if that's not a big deal and/or if you want to watch all the games then TSN might be a better option.
