When using the Charge attack after Lunging with the spear, Bedrock forces you to wait roughly 0.4 seconds before being able to use the charge attack. On Java, its nearly instant and as such the lunge attack can do much more damage when playing on that platform.
*To Reproduce
Enchant Netherite Spear with Lunge 3 & Sharpness 5.
Lunge at full health creeper using jab then charge. on Java you can easily one shot it.
Much more difficult to do on Bedrock unless using Elytra to maintain momentum, even when hopping and lunging.
Looking at the Wiki page for Lunge, the GIF has the lunge and charge usage. You cannot at all do it that fast in Bedrock.

Confirmed. This entire section of the wiki is inapplicable in Bedrock Edition. https://minecraft.wiki/w/Lunge#Charge_attack
That seems like a significant disparity.
