There are no real perks to joining any of the factions the only real benefit is access to multiple shops with near identical inventories.
Benefits to siding with the institute.
The institute allows humans to live in a clean safe comfortable environment free from the strife and environmental hazards present on the surface.
The institute gives you relay grenades which are useful and can be used anywhere to call in syths to fight for you.
Personally i like the bos things a bit better but that might be a carryover from the original fallout and fallout 3.
Jobs are waiting what s holding you back.
Siding with the brotherhood also allows players to form an alliance between minutemen and the brotherhood.
Over the decades of isolation and development the institute has developed a very effective system that maximizes efficiency and promotes individual development and research.
They have captured hundreds of men and hundreds of women to dip in the fev for science.
The institute thinks technology can help humans survive for long in such post apocalyptic boston.
You get a near perfectly safe base filled with new junk items and science stuff.
Namely you don t get 3 extra towns complete with vendors to go to.
The brotherhood of steel also had similar goals but with different intentions.
You can step on the jobsite as a vinyl siding installer right now with no prior experience and earn up to 70k.
In fact if you go deep with any faction you only lose benefits.
Build success beyond the desk you don t need a college degree to have a successful career.
Siding with the institute it s a shame they don t let you play a more lawful evil toned character as really i find it hard to imagine the sole survivor as the voice actor portrays them ever siding with the institute.
My favorite so far is the minutemen.
At the institutes we provide educational support resources and leading research to help those in risk management and insurance better serve the public.
Siding against the railroad means you d be picking up more reinforced railroad coats gauss rifles and raillway rifles.
The most important.
You get the teleporter which once the new hardcore mode comes will be the only way to fast travel in that mode.
And then terminated them.
I also like them since their only objective is protecting people.
