I can agree with that. Since the crystal was broken in half, it would’ve been interesting if the lightsaber at least had a unique effect, like Kylo’s saber, or even a different color but the same hilt. I think someone said the Visual Dictionary mentions that Rey “healed” the crystal, and I can understand how having Ben using the lightsaber after he is redeemed hold some thematic weight, but I think it the blade having a noticeable difference would’ve been more interesting for the audience visually.
