You also get more money per game (league, cup, CL) but everything costs more. The players you need cost more. Well more precisely, what you were paying for a 4* you have to pay for a 3*. So, why wait? Yes you get more for your tokens, but less for your money. If you can get some good investment players, ones that will survive the drop in star level when you get promoted, then it is worth buying.
I tend to go for older players at the end of the season then release them. They are cheap, highly skilled and do their job. But they are injury prone and likely to retire on you, but who cares about retirement, you're gonna get shot of them anyway, it's cheaper if they retire.
