High frequency systems just typically have worse sparks due to a number of

1. dielectric losses are higher at high frequency
2. Coronal losses appear higher
3. small capacitors in HF systems mean lower power and less brilliance in
any sparks thus produced.
4. smaller capacities in the terminals limit spark length and color

It is hard to conceive of a 2 mhz coil system spouting 5 foot white hot arcs
using normal Telsa coil construction methods.

In general, most coils under 500 khz are in the toilet spark wise due to a
any or all of the above reasons.

I think the argument offered about the higher frequency, higher energy
between 500khz and say 2mhz is just not a real item of concern where real
sparks are made and show just how fine hairs are being split on non-issues.
