It really rather depends on what the modern Sonnet-writer is doing. A modern sonnet-writer might well adopt the rhythm, rhyme scheme and general structure of Shakespeare's sonnets. In this case, the only difference would be that they are different poems which is obvious.
Shakespeare's sonnets are known by numbers, written in Roman numerals. Therefore three of them are Sonnet I, Sonnet II and Sonnet III. Or you can pick any three numbers up to and including CLIV.
Sonnet's 99 and 126
Sonnet XXX. Shakespeare's sonnets do not have titles, just numbers.

Shakespeare's sonnets are not a sonnet sequence in the same way that Spenser's Faerie Queene is. Sonnets with similar themes seem to be grouped together but they do not combine to make a coherent narrative, as sonnet sequences do. When the sonnets were published in 1609, there were 154 of them.
A Shakespearean sonnet is a form popularized by Shakespeare which consists of the rhyme scheme ABAB CDCD EFEF GG and is written in iambic pentameter. It stands in contrast to, say, Petrarchan or Spenserian or Occitan sonnets, which employ differing rhyme schemes and meters. _______________________________________________________________________ In other words, Shakespeare's sonnets were written by himself, regular sonnets aren't. It's really as simple as that... And besides, all sonnets are written in Iambic Pantameter and consist of fourteen lines.
Sonnet XC. Sonnet XVIII. Sonnet XXXV. Sonnet CL. The Sonnets do not have names, only numbers. If you want the content of the various sonnets you will have to read them. The attached link is one place you can do this (also any copy of the Complete Works of Shakespeare)
Some of the sonnets Shakespeare wrote include "Sonnet 18" ("Shall I compare thee to a summer's day?"), "Sonnet 29" ("When, in disgrace with fortune and men's eyes"), and "Sonnet 116" ("Let me not to the marriage of true minds").
They don't have to be; but it is understandable that people might think of them that way. The reason is that throughout history, some of the most famous sonnets have been about love, especially certain sonnets written by William Shakespeare. Among Shakespeare's many sonnets about love are Sonnet 18 ("Shall I Compare Thee to a Summer's Day"), Sonnet 105 ("Let Not My Love Be Called Idolatry"), and Sonnet 130 ("My Mistress' Eyes Are Nothing Like the Sun"). I enclose a link to a site that has all of his sonnets.
