Depends on the shade of green you want, and if you want it to be nearly monochromatic or not. And if you want to be able to quickly switch between white and green. The 'green valley' in that graph shows where you don't get much light. Red and cyan are weak in white LEDs.

Green LED's are super awesome.

If you just want green, get a Green LED. If you want white, but sometimes use green, either get a green filter, or get something with two LEDs, a white and a green one.
Using a filter is not very efficient because any light that is not green is lost.

I spent about 5 yrs experimenting with green lights. They are great but using any monochromatic light is a learned experience with a steeper learning curve for some than for others. IMO that is why so many who try them out often give up after their first use. I eventually got pretty comportable with 525nm.
One of mine has died but I still have all the rest I bought over the years.
I'd go with the green LED over the filter any day.

Each additional surface also causes light loss.
