If you want to go even more advanced (and entirely silent) estim is also an option, although they do require diffirent script types. But a good set of this isnt cheap either (good powerboxes are often expensive, and for funscripts they must accept something like an audio channel).
But being analog, and providing multiple channels, it can offer quite a bit. And that makes them very suitable for funscripts.
And estim orgasms on that do differ from normal ones. So on that part it even allows variety to stroking. And even in estim there are quite a lot of setups you can do. As you can choose to have it involve an estim butplug, and you can choose whether a contact point is on the tip, shaft, base. Depending on the powerbox even direction (+/-) matters.
And its not like ‘scripts’ are truly hard to obtain either. CH videos have a lot of these on milovana (usualy as an audio file). But even without that, i already made a conversion tool to quickly convert any script: https://discuss.eroscripts.com/t/convertvib-for-ofs/102955/5 (note, the thread is about a diffirent script that goes the other way around, but this post does the conversion).
And as a last suggestion: buttplugs can make you more sensitive overal (a good one causes constant stimulation), so even if they dont follow funscripts. They can assist slower less powerfull devices into still getting you off. All that is needed here is a good buttplug. Which you can recognise while using it, basicly any movement you make should already stimulate (which especialy when gettig close to orgasm helps, as you are most likely going to move a bit then).
But as all toys: when overusing a toy/setup, you can get used to that, and by that become less stimulated. Variety remains important.
