Some people like to hold the opinion that A is superior to B in many ways. Others however, contradict A. Personally, I would prefer (表明自己的观点：赞同A) because I think A has more advantages.
There are numerous reasons why (表明自己的观点：赞同A) , and I would in here explaining a few of the most important ones. First and foremost, the main reason is that (赞同A的原因之一). It can be given a concrete example:(举例说明原因之一).
Another reason why I advocate the attitude of A is that (赞同A的原因之二). Take the case of thing that (举例说明原因之二)
Last but not the least, one very strong argument in favor of A is that (举例说明赞同A的原因之三). This demonstrates the undeniable fact that (表明A的优势)
Of courses, choosing B also has advantages to extent. For instance, (列出B的1-2个优势)
But if all factors are contemplated, it is no difficult to conclude that the advantages of A carry more weight than those of B. From what has been discussed above, we may finally draw the conclusion that (总结观点,呼应文章开头).
No doubt, I choose A in no hesitation, because there are too many benefits about A that outnumber its disadvantages and I feel no inclination not to choose it. But B, on the other hand, has advantages no more than its disadvantages. But any argument remains groundless unless we manage to present plenty of evidence to support it.
The most important benefit of A is that (A能带来和第一个好外). A case in point is that (举例说明A的第一个好处). To achieve the same effect, B will (B带来的坏外,比如：浪费很多东西，如时间，金钱等).
Another benefit of A, which B can hardly achieve, is that (A的第二个好处). Let us take an example to illustrate this point: (举例说明第二个好处).
Although B also has its seemingly profound advantages, it can only be achieved conditionally because (B的局限性,即这种局限性是很难改进的).
After understanding the above reasoning, it is quite safe now to say: to choose A is nothing but a wise action.
