The decent brand and the knock off version we’re actually my favourite funnels for a while but the Option-O Lagom p64 funnel is a little better because it’s thinner, it actually fits better for different portafilter holder forks where the decent shape is nice but obstructs more of the ears on the portafilters so doesn’t work as universally as the Lagoms does.
Unfortunately not sure if they sell those separately.

One I didnt mention was the Kafatek Monolith flats it actually has the ledge that goes in but not too deep, but is also thin so works well with other holder forks too.
