First of all, the tool that suggests you're being routed through US/BR is using geoip information that seems to be incorrect (also you'd ping much higher than 100ms). But you are suffering from poor routes through Sweden and Poland, which is not ideal if you're from Croatia.
Your Dutch/i3D route (Bolus/KroketBrigade) looks alright:
Pretty much what you can expect, mostly a direct route.
Your German/Hetzner route goes via Stockholm adding 2x1200KM to the route:
Your French/OVH route goes:
This is beyond dumb.
The three German machines are located with two different datacenters. DusselBrigade is myloc.de, Fakkel/NewBrigade are at Hetzner. The two Dutch machines are located at i3D in Rotterdam. Baguette/PhoenixBrigade are with OVH in France. We purposefully use a bunch of different datacenters, so there's always one that pings/routes well.
tl;dr your ISP saved a buck or two on routing
