I have a hand missal in my traveling Mass kit. It is quite convenient as it has all the texts that I need when I am traveling.
I see much fewer people using a hand missal than I did, for example, in the years just after the Council.
I think they are a great help, for example, for those who are hard of hearing or who otherwise have trouble hearing the texts proclaimed/declaimed. It is really a matter of personal preference as to whether or not having the text in front of you to follow along is a help or not.
In my experience, many find a worship aid such as a missalette, the
Prions en Eglise [which is a French publication] or such more useful than the hand missal as the texts are presented such as to require less flipping about and the use of ribbons.
The altar edition is the missal as you see it on the altar of your parish. I would not recommend that at all. It is an extremely large and heavy book which is also distinct from the lectionary, which is its own set of large and heavy books. It has the text of the Mass together with the rubrics for the sacred ministers. For a lay person to bring such a book as an altar edition Roman Missal with them would be eccentric in the extreme. It would also be very cumbersome to use in a pew; it normally has its own stand on the altar as it is too heavy to hold for prolonged use. I dare say that those about you, and the priest, would find it bizarre…not unlike having your own edition of the full sized Evangelarium from which the Gospel is proclaimed at the ambo.

The chapel edition is the missal at about 2/3 the size of the altar edition. As its name indicates, we use it in chapels where we do not need the book or the printed text in the missal to be so large – such as the more intimate setting of a chapel where the altar is also normally smaller.
This will give some comparison.
