Let's break it down. With hot whisking, you're paying for:

• The whisk: affects foam quality and ease of use.
• The bowl: helps with whisking and holds heat.
• The technique: time and practice to get it right.

With iced prep, you're paying for:

• The shaker or frother: speed and convenience.
• The glass or tumbler: aesthetics and insulation.
• The matcha: the same powder, but you might choose a cheaper grade.

Neither is objectively better. Hot whisking gives you a more complex cup and a meditative ritual. Iced prep is faster, cheaper, and more refreshing on a hot day. You decide which matters more.
