Not a all. As a phonetic enthusiast I can assure you Pinyin is by far the worst representing Chinese sounds with English letters. It is made to represent Chinese phonetic, but its creators are seemingly completely ignorant toward basic phonetic rules, such as voicing and aspiration, and how words actually sound in English.

As an example, b in English is called an unaspirated voiced consonant, which means you vibrate your vocal folds, but send only a little breath when you sound it. You can compare it with p, its aspirated voiceless counterpart, for which you do not vibrate the vocal folds (voiceless), but sends a strong breath through your month (aspirated). Chinese does not have most voiced consonants present in English, so Pinyin naively uses b (also d and some others) to represent voiceless aspirated consonants, which does not sound like a b, but more like p in “spade”. This results in most of the foreigners learning Chinese with Pinyin bringing English pronunciation when they speak, and makes them sound way too stiff and thus awkward.

Wade-Giles, in comparison, is much more systematic, and does a much better job hinting speakers with European (especially Germanic language) background to sound more correctly. Bopomofo does not have this problem, as it basically invents a new set of scripts. Pinyin probably lets you pick up casual speaking Chinese most quickly, but beyond that, it’s a curse.

[Edit]: Voice “folds” not cords, sorry. Also fixed some typos.
