A level 105 boss is more than 6 times what it was last time, while the 150 boss is only 1.05 times what it was last time.
So, yes, overall the difficulty is quite a bit higher - however, when you're struggling on that 125 and the past memories come up telling you, "if you struggle on a 125, a 150 will be impossible", tell those thoughts to go away because this is not the boss you're used to. If your team can drop a 125 in 60 minutes, you can drop a 150 in 90 minutes. Boss 150 is only 1.4x the HP of boss 125.
