IMPORTANT! If this is your first time watching, then it's strongly recommended you watch this series in Release Order for best enjoyment, this is because the author planned the story out of order, and watching chronologically spoils some parts, while not knowing what happened before creates a more interesting story.
If you already watched the whole series, then it's ok to 'rewatch' in chronological order so you can understand it better, or just get a different experience:

Not exactly a Watching Guide per se, but a collection of animes with Great Art!
I haven't completed Gintama yet, but a lot of people have been asking me about it so here it goes:
Gintama is largely episodic with most arcs just taking 1-3 episodes at the most, and although some jokes do rely on what has happened first, it's probably just necessary to watch it in release order. There are no episodes to skip since it's a comedy, each episode is either a hit or miss, so just skip to the next episode if you don't like what you see, the next one will be better for sure!
The series' story is divided into small arcs called 'Cases':
The 1999 version has more detail of the earlier events and it's better at giving you an insight into the character's observation skills and way of thinking, it focuses more in the puzzles and critical thinking, it also has a darker tone than the 2011 version which focuses more on the action, fun, and it's more kid-friendly. The 2011 version quickly recaps the first arcs, missing crucial insights that make the story shine, so I recommend you start with the 1999 version and subsequent OVAs, then jump to the 2011 version at Episode 75 (or Episode 54 if you skip the OVAs or you are watching the Dub). You won't be missing any major events if you decide just to watch the 2011 version and if you are not into dark animes then you may prefer this version (not that there is more gore or violence but rather the way the story is told).

Mobile Suit Gundam: Where to Start and What's Worth Watching by Lauren Orsini
Fans often loathe this installment for adding lots of terrible comedy in an effort to lighten the mood of the show, some people may say that it picks up in the latter half, but that is still not on par with the quality of the previous series.
But if you still want to watch, these are the Episodes that contain the main story based on this post, and trim down a little more to leave only what is relevant:
Note that the first story and probably the best of them all is actually the last 3 episodes of Ayakashi - Japanese Classic Horror (Bake Neko Story), which is the best part of that anime to such extent, that spawn this standalone series. So you should probably start there.
