Similar main male MC with a vaguely similar vibe. Mutou to Satou is much simpler, but chances are if you like one you will at least find something you enjoy in the other.

Hanazono-san Chi no Futago-chan

Both series feature a love triangle with similar character archetypes and dynamics involved. Hanazono Twins is definitely less extreme and has significantly less ecchi and drama, but the similar characters and dynamics may connect with a similar group of people

Kimi wa Houkago Insomnia
|
While the subject matter is incredibly different between the two, I think the growing romance that they both feature brings about similar emotions. Though, I must specify that Buzzy Noise focuses much more on depression and how that affects a grown person, while Kimi wa Houkago Insomnia is a relatively simple High School Romance manga. I mostly connect the two due to a similar feeling, rather than any real similar ideas.

Kimi wa Houkago Insomnia

Both series utilize an oddly ethereal tone to heighten strong emotional moments. Their subject matter may diverge a little, but the choice of setting along with the Japanese High School Romance give both of them a vaguely similar vibe

Fujiyama-san wa Shishunki

...then you might like
Kimi wa Houkago Insomnia
|
Both series are by the same author within the same genre and tone. That alone is a pretty decent reason why someone may enjoy both. Both series feature a boy and girl growing closer and building up a connection. The impetus for this varies between the two, along with the characters being all very different. "Fujiyama-san wa Shishunki" is more ecchi than "Kimi wa Houkago Insomnia"

Mousou Telepathy

Both about a girl suffering from perverted thoughts due to the influence of a person in her life. They are also both romances, but Ao-chan takes a distinctly more Shoujo-esque direction with it.

Hajimete no Gal
|
They both take a pretty similar base concept of a Gyaru being smashed together with a loser Otaku, but they do go in pretty different directions. Hajimete no Gal takes a more ecchi "comedy" approach while Real Girl goes for wholesome Shoujo. I still put up this recommendation for the concepts being similar, but the difference in style might be too big of a turn-off for people

Ponkotsu Fuuki Iin to Skirt-take ga Futekisetsu na JK no Hanashi
|
Has a similar premise with an uptight Student focusing his attention on a more lax student. The actual application of this idea varies wildly with Arakure being much more lewd while Ponkotsu is more wholesome, but they are similar enough that I can see people liking them both

Himeno-chan ni Koi wa Mada Hayai
|
Both manga follow a childhood romance that more or less makes very little progress every single chapter, centered on a more assertive party trying to entice a more passive party. They also share a surprising similar art style

Soredemo Ayumu wa Yosetekuru
|
Both feature a straightforward guy interacting with another girl. Aharen doesn't feature nearly as much focus on romance, but the general vibe both series give is pretty similar. Soredemo is probably just a little more down to Earth.

Suki na Ko ga Megane wo Wasureta

While these two vary wildly in terms of progression, humor, and story structure, the actual style is very similar. Both use a seat-neighbor helping out the other because of a growing affection.

Yancha Gal no Anjou-san
|
Both utilize the structure of a Gyaru girl teasing an unpopular and scrawny dude that she clearly as affections for. The only thing that really separates them is the style of the teasing and the utilization of the side characters.

Grand Blue

...then you might like
Gokushufudou
|
Both have a sort of down to Earth comedy that rely on contrasting facial expressions. While they vary wildly in their approach to story, the way they utilize comedy makes me think of them in a similar vain. Though it should be noted that Gokushufudou doesn't utilize Ecchi while Grand Blue does.

Jitsu wa Watashi wa

It has a similar off-kilter feel to it's romance and progression that while not all together similar, has a very similar vibe. Both are deeply flawed series that have such an impressive style to their stories that I can't help but love them.
