Those are definitely buff, just bear in mind that Infitech has its own progression rate and balance points. Mekanism pipes wouldn't work by default because they're way too powerful; nobody would have any reason to use anything else.I have used EnderIO in the past and greatly appreciate the singleblock/multipurpose capabilities it's pipes offer. I have 2 gripes with it though. It makes the pipes small and necessitates opaqueness; I really like to see the liquids/items in pipes. The second gripe is that they do not flow very fast at all; max 800mb/t whereas mekanism's flow is 64000mb/t. Additionally, the extract rate of a single connection is 200mb/t for enderIO and 6400mb/t for mekanism. Again, a vast difference. I also think the mekanism pipes are more visually appealing acknowledging the fact that enderIO pipes are more functionally diverse.
For me, I use enderIO for compact/hidden builds and logistics pipe/mekenism pipes for builds where form matters. So, my brewing station automation will definitely use enderIO. My IC2 fluid reactor will be large and appealing looking so, mekanism pipes.
I really like how MysteryDump did her plant:
In places where restrictive fluid flow cannot be tolerated, mekanism pipes again will be used. It is a set it and forget it connection so that I do not have to spam the side of my boiler with connections to get the flow rate right. That just looks messy to me and with mekanism pipes, unnecessary.
