Hadouken & Kikoken
The "All About Street Fighter Zero 2" strategy guide didn't have any translations. So, I asked some very generous translators from Reddit to donate their time. Special thanks to u/jodanj for the immaculate translations and for double-checking other's contributions. Some of these stories have interesting pieces of lore, while the rest are character-focused. Enjoy

The principal difference is stated by the name, "Shin" (True) states that the user is focusing all his might into that Shoryuken, focusing to make it stronger, "Metsu" (Destruction) by the other way, is a term used mostly by those who're possesed by the Satsui No Hado, even the kanji used by Akuma's SFIII taunt/Kiai and by Evil Ryu/Kage on his back and his Shun Goku Satsu (滅) it's "Metsu", meaning that the Metsu Shoryuken it's a Dark Hado infused shoryuken.
The second difference, the one it discovered recently, is that the Shin Shoryuken starts with the right hand and ends with the left one, while the Metsu Shoryuken starts with left and ends with right (all using the character in the left side of the screen).
To analize more, in SFV we see Sagat infected with Satsui No Hado arround the scar that Ryu marked with a Super/Ultra Combo Shoryuken. The scar's trace implies that the Shoryuken was done with the right hand of Ryu. Taking all that in count, we could say that the move used by Ryu to scar Sagat, was not a simple shoryuken, but the Metsu Shoryuken.
To complete this, is neccesary to state wich one of them is stronger, in my opinion, seeing Shin Shoryuken as the EX shoryuken in SFV/SFXT and the Metsu as the epic Ultra Combo in SFIV, I would say that the Metsu Shoryuken is the more powerful version, between this two, however, Ryu is starting to control the Satsui little by little, the Metsu Hadoken/Shoryuken are proof of that, so, if the Shin Shoryuken is a full user's power version, then pheraphs Ryu will develop a most terrifying Shin Shoryuken than Gouken's once he's fully able to use the Dark Hado.
