Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents). Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference.

I tried sticking to discord.Client then I found that there are more features in commands.Bot. Then I found errors when using commands.Bot.

An example of this is:

When I try to use commands.Bot

client = commands.Bot(command_prefix=">",intents=intents)

async def load():
    for filename in os.listdir("./Cogs"):
      if filename.endswith(".py"):
        client.load_extension(f"Cogs.{filename[:-3]}")

The above doesnt giveany response from my Cogs and also says

RuntimeWarning: coroutine 'BotBase.load_extension' was never awaited  
  client.load_extension(f"Cogs.{filename[:-3]}")
RuntimeWarning: Enable tracemalloc to get the object allocation traceback`.

Then when I try to use discord.Client

client = discord.Client(command_prefix=">",intents=intents)
async def load():
    for filename in os.listdir("./Cogs"):
      if filename.endswith(".py"):
        client.load_extension(f"Cogs.{filename[:-3]}")

The above also gives me an error: Exception has occurred: AttributeError 'Client' object has no attribute 'load_extension'

Which one is better in the long run? What is the exact difference?
