This question is opinion based, and my answer is therefore opinion based. But I think it's worthwhile talking about balance here, since you did mentioned this in your comment, and balancing logos and text is all part of graphic design.
Here are some observations.
I am not fond of the first three examples, but that's down to personal taste. If you or your client likes them, then fine.
The bottom two logos look imbalanced with the text to me. The problem here I think is caused by the asymmetrical nature of the letter P, which makes the line of text look too long in the bottom left example.
The bottom left example uses normal text rather than italic which is somewhat jarring to the eye. The logo is italic, and to match its slope, I think italic text would look better.
The kerning of the logo letters needs improving. In the bottom left example, the D is too far from the T, and the T is too close to the P.
The example with the text above the logo is a bit odd to me, since it doesn't read right in English. It reads like "Shipping Solutions DTP" which is strange. Therefore I would reject that design.
I realize you are probably trying to make the length of text in the bottom two examples exactly the same as the width logo, but geometrically perfect size matching can end up looking imbalanced, especially if your logo has a letter which is asymmetrical like the large letter P.
It's often necessary to adjust positioning by eye, making an adjustment to make things look more balanced to the human eye, even though they may no longer be geometrically perfect. This is often known as "optical adjustment". Basically, you adjust it until it looks right - which of course is subjective. But your eye and brain is as good as any other, and most humans perceive things in similar ways. Add to that the fact you have already noticed that, and you already have the feeling that something is not quite right.
Anyway, here's an example/suggestion on how I would go about fixing it. Notice I say "I" because other people might have other solutions that are equally valid. This is where it gets quite subjective.
Use italic text to match the text of the logo
Adjust the kerning of the logo.
Reduce the point size of the line of text to make its length shorter, to compensate for the asymmetrical letter P at the end of the logo
Draw some guide lines to help you with the positioning.
Rather than have the text align with the extreme edge of the curve of the letter P, bring this in a little to compensate for that imbalance.
Something like this perhaps
Thank you!
