Both have a similar feel to them, primarily that they share some plot similarities towards the end of each of them. Both pairings are somewhat similar cliché characters hesitating and engaging in a forbidden relationship cause brother/sister. If you enjoyed the ending of one, I think you'll enjoy the ending of the other.

Both are romances between a step siblings, focusing around a big secret she's keeping from him. Liar x Liar is a far longer and more serious manga than Imasugu Oniichan, though they share a lot in common, if you liked the antics and bro/sis pairing in one, you might like the antics and pairing in the other.

Both manga's depict the everyday life of siblings who are in this quasi-incestuous relationship. In both cases one sibling is clearly interested in that form of relationship and the others feelings aren't fully established. Both have sidecasts of more siblings, Though in Futaba-san the sidecast are in a similar situation to the maincast and in Siscon Oneechan the sidecast just builds on more interests in more directions (though the initial younger sister seems uninterested so far in anybody) Both are quirky romcoms with layers of coincidences, Only main difference is one is shoujo-ai.
