There's a lot wrong with the Pro/Cons sections. Using a good softmod is better than almost all Modchips, because while some Modchips fail at games like NSMB, softmods can support patching of games at runtime, while Hardmods may require a patched ISO.
There really is no difference between pros and cons. The single biggest difference between hardmods and softmods is brick recovery, but if you have a Wii with the boot1 exploit that eliminates that advantage completely.
Softmods aren't slower than Modchips either, it depends on your loader. Most loaders play at full speed without error.
Nintendo updates actually DO break modchips as well. You usually wait for an update from the company. Same with Softmods, you have to wait for an update. But then again, both modchips AND softmods allow you to block updates.
There's really no comparison. The single reason (and the ONLY valid reason) to get a modchip is if you don't have the boot1 exploit and want to be bricksafe. Even then, you can simply run backups via SNEEK (NAND emulator), saving you money.
At one point I actually considered getting WODE for the promised ISO streaming, but that isn't even available yet so I'll pass, and even if it is, it's probably going to have gigantic problems (read:SLOW), and I've already heard a lot of issues occuring with WODE.
