Lightning Spear Techniques are somewhat common in the Khun Family (e.g. the Hell Train Khun and Asensio seem to use them).
The Maschenny Style Lightning Spear technique is unique to the Maschennies and is considered "one of the ultimate Spear Techniques". It's a specific Lightning Spear technique, not the only one.
Kallavan and Lyborick's dialogue sounds like Lyborick was imitating a general lightning Spear Technique and not Maschenny's in particular.
If Lyborick was of Maschenny descent, he wouldn't need to imitate an inferior technique, since he would be capable of utilising an ultimate Spear Technique.
Of course all usage of the Maschenny Style Lightning Spear pale in comparison to Maschenny's own usage of the Technique.

Considering that Lyborick is only imitating the ordinary Lightning Spear (not an ultimate technique like Maschenny's) and considering that Kallavan only said that he's (much) stronger than the
average Lightning Spear Bearer, I expect Master Spear Bearers like Asensio to considerably exceed Lyborick as a Spear Bearer (of course, Lyborick's other abilities may bridge the gap, but evaluating them solely as Spear Bearers and considering only their Lightning Shinsu Quality, Asensio should be well above Lyborick. He's not regarded as "
the Spear Master" of the Khun Family for nothing).
It goes without saying that Maschenny Zahard is in another class entirely as a Lightning Spear Bearer (the inventor of an ultimate Lightning Spear Technique, her usage of the technique vastly exceeds the usual High Rankers, and even among the Maschennies, she's the only one that can utilise the technique to its full potential).
She's probably second only to Eduan in the category of "Lightning Spear Bearers".
To be frank, my main takeaways from the chapter on this topic are:
- Lyborick is not actually all that strong as a Lightning Spear Bearer.
- His real talents may lie elsewhere, especially because his "shape" is not a spear and he has Po Bidau genes.
- He's only imitating the ordinary Lightning Spear technique, so it should pale in comparison to the Lightning Spear techniques of other Elite High Rankers.
- Granted, Kallavan said that he's probably much stronger than the average Lightning Spear Bearer.
- The level of Elite Lightning Spear Bearers should considerably exceed what Lyborick is capable of.
- Their genuine article should significantly exceed his mere imitation.
- Depending on how Lyborick's Lightning Spear Bearer abilities stack against a serious Kallavan, I'll need to reevaluate them.
[ until further notice, Asensio is significantly stronger than Lightning Spear Bearer Lyborick (all out Lyborick can very well be a different case), but if you restrict Lyborick only to his lightning shinsu and his Spear Bearer abilities, he should fall well short of "Spear Master Asensio".
